How would that hand the case of pkgA and pkgB both needing
update and both being dependencies of firefox?

This could be a simple as (effectively) running -g and comm -3 on
the result and original file, unless you want some magic with
'top-level' vs dependencies, then it gets more fun.

This would be the fun :) Would a straight variation of
-g which only lists the top level packages be fine?

That would be a nice feature.
