Altering the set of directories as showsn by .libPaths() ? This could be as
easy as setting `R_LIBS_USER` or `R_LIBS_SITE` or calling .libPaths().

I wish to check if an update to package B will break some of the reverse dependencies of A and/or repair broken reverse dependencies of A. It is obvious to update B on CRAN but this may lead unnecessarily to a number of CRAN updates.

We have similar issue with CI Runners, RHub, win-builder -- they may only see
the fixed set of CRAN packages and versions, and/or system libraries.  Plus,
these days getting an update onto CRAN is no longer as simple as it used be
(unless the package is small, in excellent health, and without many reverse
depends itself).
