I think that would solve my original gripe, if I understood the idea.

So instead of the typical "reject" instruction we also add a
"rejectverbose" instruction that has a more verbose message. Docs would
describe it as an additional instruction to assist with debugging a
complex pg_hba.conf, with warning that if used it may assist the bad
guys also.

"pg_hba.conf rejects entry for host..."

Patch for that would be simple and clear; I can add that if we agree.
