I might be wrong but I thought all package in Imports, LinkingTo, Depends and
Suggests are actually checked for availability.
CRAN and BioC work by default, others can be added via Additional_repository
in DESCRIPTION. And as I recall, not mentioning one leads to some complaint
from R CMD check. But I may well misremember.
