If the code is ignored nowadays, can I put a vanity value there, or do I have to keep it “????”? I noticed (due to work in another thread) that Safari has a creator code (“sfri”), and I think TextEdit reuses TeachText/SimpleText’s creator code (“ttxt”).

In theory the code might be used by a Carbon app running in a very old version of Mac OS (e.g. Classic environment or pre OS-X) but I expect you can count the number of those systems still running on the fingers of one hand.

Maybe there's a dust-laden cobweb strewn room somewhere in Apple's basement, long forgotten, where a lonely phone rings whenever someone tries to register a creator code, but the guy that used to answer it has long since died and nobody's noticed yet.

You can't register those anymore. (For a very long time now. )
They probably persist mainly to support legacy files that might not have an extension or other way to identify the right apps to open them.
Pretend they do not exist unless you're handling really old data from the 80's and 90's.
