If you are asking for an optional feature that would display these
indicators as we did 15 years ago, I'm okay with adding it.  (We
already have quite a few optional variations on similar themes, but
one more cannot do too much harm, I guess.)

My interpretation of what you said originally was that you want to
unconditionally revert to pre-22 behavior, which is quite a different
request.
