Several packages in :core do depend on compat. The idea is to use
(require 'compat nil 'noerror), which does nothing in core, but enables
forward-compatibility features on ELPA.

Sure, that works, your right. And it's a good idea. 

But it doesn't solve _this_ problem even if compat.el patches package.el, because once you get Emacs 29, you're locked out of ELPA Eglot (unless you take that very circuitous route).

I agree that it is slightly out of scope of compat. But this particular
problem appears to be important enough as exception.

Yes, but more importantly, i don't think there's a fix to this bug that can be done fully ELPA-side.
