As I recall, the way we allow superusers to set role to other roles is
by considering the superuser to be a member of every role.  Now, I agree
that such an approach doesn't make sense for pg_hba consideration.

Perhaps the superuser-override should be moved to be at the 'set role'
level instead of setting things up such that the superuser is considered
a member of every role.  That would fix this but would require adding a
couple of additional special superuser checks, which isn't something to
do lightly, imv.
