I don't know if it's considered officially supported, but I often use
pg_ctl stop on a directory without worrying about whether I'm doing it
with the same server version that's running in that directory. I'd be
reluctant to break that property. So I bet our ability to modify the
file format is already quite limited.
But again, no issue with having a way for pg_ctl to fish the
information out of there.
