Yes, I am of course very aware of the issue.
But we had to separate out R-release and R-devel for years, and so I did. I
had separate libPaths (or, at least, leading component) for R-devel because

It was the R_LIBS_USER (which used to work) to R_LIBS change that got plus
the fact that my R-devel was picking up my R-release check.Renviron. The hint
from Martin got rid of that.
Sometimes I wonder if we should have an extra-verbose mode that picks up
EVERY single Sys.getenv() and alike to make it easier to trace this. But
run-time cost of the check is probably unattractive.
