@module-rebuild is a dynamic set. It translates to "all the packages you
have emerged that install out-of-tree kernel modules"

So not really a fair comparison. Compare instead against a regular
static set - "a bunch of packages defined by you that go together and
live in /etc/portage/sets/<set_name>"
