I may be mistaken, but IMHO the main benefit of unicode identifiers is
to allow non-anglophone programmers to name things in their native
language, with accents and diacritics and so forth.

For those programmers, typing such identifiers is already easy, as those
characters will be on their local keyboard layout or input method.

Developers doing a lot of math work should have some such mechanism
already in place - keyboard macros come to mind - since they'd also have
to type all that into the docs.

As for making it easier to use obscure characters/emojis in identifiers,
I'm in favor of making that rather difficult :-)
