What about adding a second group syntax that only evaluates explicit
memberships? That way, everyone could pick which behavior they liked
better, and Alastair's suggestion could be done that way, too:

host all *personae_non_gratae 0.0.0.0/0 reject
host all +foo 0.0.0.0/0 md5

If, as Josh said, few users even know about the old syntax, there should
not be much potential for confusion in adding a new one.

Additionally, most things that can be done with groups in pg_hba.conf
can also be done using CONNECT privilege on databases.
