a) That is in conflict with what was said in the past; we have used an
explicit min version of 10.14 for the C++17 we were using then (and we now
need a bit more so 11.0 is welcome).

b) That is in conflict with how I read the R manual I quoted: R Admin,
Section 'C.3.10 Building binary packages'. Recall that our package uses a
binary artifact (by permission) so we have to play along and this minimum
version used by both matters.

c) That also appears to be in conflict with empirics. A quick search [1] at
the searchable CRAN mirror finds around a dozen packages doing just that:
setting a minimum version.

Anyway -- I 'eventually' got the info I need. 

Best regards, Dirk
