What seems more likely to be useful and to not break anything is to push

Only after that work is complete and there's been a reasonable amount of
time for clients to start relying on it can we really start thinking about
whacking the message texts around.

+1, but...

does psql do anything with those fields? ISTM the biggest use for this info is someone sitting at psql or pgAdmin.

Maybe schema info could be presented in HINT or DETAIL messages as well?
