Great, thank you very much! I'm already looking forward to Emacs 30 now. :-)

Oh, wow! You went far there. I had only thought of a simple
`font-latex-add-keywords` for them when I mentioned.

I did take it for a spin (light, but should be sufficient for this).
And it does more than I'd expect, you are even handling the insertion
of the sets. Fontification is fine too.
For these macros, seldom used, macro insertion on the AUCTeX side with
TeX-insert-macro is more than sufficient. Pretty good, looks good to
me. Thank you!

Sure, the peculiar bibkey notation still defeats
`reftex-view-crossref', but... as previously discussed.

Use this stuff as you see fit. As I said, just to get some ideas from.
Discuss if you feel like it, but feel free to keep it to yourself too.
I offered without giving it much thought, and it turned out to be
quite a lot.
Take it as an example of what an interested user had to do to add
support to a few non-standard packages to this feature set in RefTeX.
I doubt the general view emerging from it is any news to folks in this
list, but sometimes a concrete example helps building perspective. I
don't expect anything to come out of it, except perhaps be a useful
food for thought to you.

Fair, and understood. And, granted, this one is actually easy to
handle on the user side (if one can live with a discrete warning face
on the backslash). I just couldn't resist poking you a little bit
about it.  ;-)

I thank _you_!

Best,
