I feel like 'acl' or 'pam' or 'policykit' are not really USE flags in
the general sense. They are more like profile settings. You don't want
to toggle these flags, you want to switch profiles. I think
conceptually profile migrations are larger changes that require a
rebuild of a bunch of stuff, and typically have downtime (e.g. where
your system isn't expected to work the entire time.)
There are practical problems with profile proliferation, but I think
it is closer to what these flags represent, if that makes sense.
