In theory, as long as the Priority fields are kept up-to-date in the
archive, then that should be a matter of just checking if a packages
is required or important, which also implies the lintian check would
not be much useful as the .deb Priority does not need to match the one
in the archive. That does not solve the additional dependencies, but
usually adding to the base system implies a discussion on debian-devel,
or automated sanity checks could be performed from time to time.
