Those who really want to run R CMD check without forcing the suggestions
can do so via setting the "internal" environment variable
_R_CHECK_FORCE_SUGGESTS_ to something "false", the test is via


If people feel very strongly about this, we could turn this into a check
profile variable to be set in ~/.R/check.conf.  Personally, both as a
developer and a CRAN maintainer I see little need in not forcing the
suggested packages at check time, as in both scenarios I prefer to act
as defensively as possible.
