Hmm, extension authors are going to realize this as soon as they try to
compile, so it doesn't seem necessary.  Having useful APIs _added_ is a
different matter, because those might help them realize that they can
remove parts (or #ifdef-out for newer PG versions) of their code, or add
new features; there's no Clippit saying "it looks like you're compiling
for Postgres 18, would you like to ...?".
