That CRAN checks cannot always be replicated outside of CRAN is a real issue.

This has been brought up before, and some of us wanted to see about improving
it, possibly relying on Docker---but as you know life is short, spare time is
generally missing, and other shiny things can distract us.  So nothing to
report yet. Which is a bummer.
