This seems like a reasonable compromise, but I think I'm OK with -C
specifying the name of the config file only. Otherwise it would be too
much logic for something that you can work around with tab completion.

I don't think I like "if not found in X then search Y". If the file is
not where it was configured to be then it's an error or it will be
ignored, or whatever the usual behavior would be.
Looking into $PGDATA is probably something we want to discourage, not do
implicitly. The backup/upgrade issue would be much simplified if we kept
hand-edited files out of there. Are you concerned about backward
compatibility? I think a note in the data directory that tells users
where to find the files is OK. Others may disagree.
Also, I'm not sure exactly what you mean with $PGDATA. If you mean "the
data area", then this would be complicated to arrange, because the data
area is or may be configured in postgresql.conf. If you mean the actual
environment variable, I think environment variables should override
compiled-in defaults, not serve as fallbacks. That's just the usual order
of priorities.

Same concern here.

Fixed locations create consistency and save typing. Both are tremendous
time-savers.
