Yes, I do think that makes sense.

...meaning that drawbacks aren't immediately visible to me right now :-)

Since elisp-shorthands is a file-local variable, I think it allows (eval)
specs.  Perhaps you can try with that, for now? I don't think it'd be
hard to add better support for such predefined groups of shorthands.

If I understand this right, then I think you may solve it similarly to the
cl- situation.

But you understand that, for the moment, shorthands are only supported in
Emacs 28, right?  Not sure where (in which versions) the library you're
intending to write would be loaded.  If that library is loaded in Emacs 27,
elisp-shorthands is simply ignored and the file is loaded normally.
