You did not specify if you look only at Debian distro repositories, or if you
include the backports managed by Johannes (which should be safe he plays
along with the r-api-3.5 tag).

I actually take the opposite view.

I am comfortable compiling from source, so this mode happens to be my
default. I use the littler scripts install.r and update.r _all the time_ to
install / update.

|    3. install.packages() inside R is /not/ safe, for the same reason.

That seems to be the same as 2. so ...

|    4. A prominent note will be posted here, when these two restrictions are
|    removed.
| Are those true statements?  Would steps 2 and 3 work if the packages don't

| are at risk without memorizing what seems like a very long list?
| If we (think we) need a new package we don't currently have installed, are
| we out of luck until 3.5.0 is officially released in Stretch?

Again, "pure Debian" or "Debian plus CRAN repos" ?
| Is there a place where an official summary of the state of the R system on
| Stretch is maintained?
| I've tried to scan this list, but I may well have missed the answers to my
| questions about Stretch.

We're volunteers so something may always fall short somewhere. Documentation
is always a good candidate.  Contributions are always welcome.
