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.
