So, is that actually an objection to the current proposal, or just
an unrelated rant?

If we think that a privilege bit on databases can actually add something
useful to this design, the fact that it moves us one bit closer to needing
to widen AclMode doesn't seem like a serious objection.  But I don't
actually see what such a bit will buy for this purpose.  A privilege bit
on a database is presumably something that can be granted or revoked by
the database owner, and I do not see that we want any such behavior for
extension installation privileges.
