Hmm, we could imagine a GUC that disables accepting a plain-text
password, all right. (We already assume the server can tell the
difference between encrypted and plain passwords.)
We already have this behavior:
regression=# set password_encryption = md5;
SET
regression=# create user joe password 'joe';
WARNING: setting an MD5-encrypted password
DETAIL: MD5 password support is deprecated and will be removed in a future
release of PostgreSQL.
HINT: Refer to the PostgreSQL documentation for details about migrating to
another password type.

Refusing plain-text seems pretty adjacent to that.
One concern is that while psql has the ability to construct an
encrypted password client-side, I'm not sure whether other clients
such as pgAdmin have grown equivalent features. Putting in this
sort of restriction would move that from nice-to-have to a
virtual necessity, so it'd put some pressure on client authors.
