I suggest that this is not a major feature.

Perhaps the work that I did to improve CREATEROLE could be considered
for inclusion in the major features list. In previous releases,
someone with CREATEROLE can hack the PG OS account. Now they can't. In
previous releases, someone with CREATEROLE can manage all
non-superuser roles, but now they can manage the roles they create (or
ones they are given explicit authority to manage). You can even
control whether or not such users automatically inherit the privileges
of roles they create, as superusers inherit all privileges. There is
certainly some argument that this is not a sufficiently significant
set of changes to justify a major feature mention, and even if it is,
it's not clear to me exactly how it would be best worded. And yet I
feel like it's very likely that if we look back on this release in 3
years, those changes will have had a significant impact on many
PostgreSQL deployments, above all in the cloud, whereas I think it
likely that the ability to have regular expressions in pg_hba.conf and
pg_ident.conf will have had very little effect by comparison.

Of course, there is always a possibility that I'm over-estimating the
impact of my own work.
