Your view, not mine. I cannot ask my employer to provide such resources.

No, this is not the main burden. For forward-facing packages interfacing
external software, it is vastly more important to track developments in
that software, by reading development mailing lists, and checking against
alpha, beta and RC, as well as tracking master/trunk in periods between
releases or when things happening in the external software seems to have
the potential to impact existing R packages. This obviously absorbs a lot
of time and energy. https://github.com/r-spatial/sf/issues/545 documents
where we were in November 2017 with this; there are lots of other examples
in posts on the PROJ and GDAL lists, and in email exchanges with others.

The problem with macOS compared to Windows has been that while providing
static builds for Windows for three iterations of the Windows RTools build
train, with help from CRAN and others, most recently Jeroen, has gone
fairly smoothly for more than ten years, macOS moves too quickly. For
Simon to keep R itself running has been an uphill struggle, with problems
with Fortran, versions of system software under clang (most recently the
archaic ssl shipped by Apple), so providing fresh builds of PROJ, GDAL and
GEOS has understandably not been a priority. We do not build Windows or
macOS PROJ, GDAL or GEOS libraries, we need others, probably close to
CRAN, to do this, following CRAN static linking policy.
Note that Brian Ripley continues to monitor and check possibilities for
static builds of OSGeo software for static linking to CRAN binary packages
for macOS, but does not have breakthroughs to report for recent PROJ or
GDAL releases, unfortunately. We are very fortunate that he continues to
help us with this. rgdal 1.5-9 is partly to resolve your problem, but just
as much to resolve problems on Solaris and other corner-case CRAN check
platforms.
Static linking isn't the only policy, but only Linux platforms provide
(fairly) mature dynamic build package managers. OSGeo4W - built on cygwin
- has been tried by some over the years, because CRAN static linked binary
packages may have different versions than say QGIS, GRASS or other Windows
binaries. We have touched on the idea of proposing R-spatial as an OSGeo
project, among other things to try to match the versions of key software
components better. But having many alternatives for source install on
macOS runs counter to this, we need to find a path that works - the
previous go-to was Kyngchaos, but that is no longer a viable solution.

Package managers were debated on R-sig-mac (yes, I follow that too). If
you use a package manager, that is your choice, but having CI for macOS
(past and current releases) then gets multiplied by the number of package
managers and environments (conda), etc. For central resources, say curl,
package managers may be OK, but get stuck when some downstream packages
either get dropped because they are not up to speed with say PROJ/GDAL, or
PROJ/GDAL get held up because the packages using them are seen as
important. This happens in all package managers, and is frequently
discussed on PROJ and GDAL lists, amonng others by those
responsible for package manager releases. The decisions are not easy, but
we cannot be held back by package managers' policy choices. My guess is
that some package in homebrew depends on GDAL 2.* and has not yet upgraded
to be able to use GDAL 3.*; since GDAL 2.* can be built (although using
the deprecated API) with PROJ >= 6, they let things slide. They should
have chosen to stop PROJ at 5.2.*, avoiding the used of the deprecated
API.

Block is your expression, what is being required is that users actively
opt in to using a very-short-life deprecated API. If I relax the
requirement (I have already opened up for using the deprecated API, which
I regard as potentially leading to positional accuracy loss, and certainly
encouraging business as usual rather than active migration of workflows to
WKT2 from Proj4 strings), I would be demonstrating crass irresponsibility
with regard to users of rgdal, who need to know that these changes (in
GDAL/PROJ) may impact their work.

Pleasant experience is not something that carries much weight. Things need
to work, and if user choices may lead to degradation through use of a
deprecated API, I feel that they should be warned, and that that is more
important than any pleaasant experience.
For many years, OSX has been checked by CRAN, and this will continue. I do
not accept that package maintainers have to resolve these problems (source
installs of packages using external software), if they follow up CRAN
requirements and make sure that the source packages continue to install
and check cleanly with successive versions of the external software.

I'm uncertain what you are referring to. I do not have a problem with
platforms, I just see the role of package developers differently, as I
explained above. At some point this year or next, the CRAN Windows and
macOS binaries will have caught up (Windows already at PROJ 6.3.1 aand
GDAL 3.0.4), so that for all users and developers but those insisting on
source installs, the temporary difficulties now being experienced will
pass. For those installing from source, when package managers catch up
with the speed of change in PROJ and GDAL, things will calm down.
