Even documentation changes?

I'd suggest installing the change as attached on emacs-28.  If that's
not possible, I'd like to install it on master, but add the same text to
the package "Commentary" section on emacs-28.

OK, I'm fine with a non-optional warning.

So these were the three entry points I see: `describe-package', `C-h f',
and running the command.  It is true that it should be enough to just
show the warning when running the command.
