Thanks, but sorry, no.  We cannot make this change, definitely not as
a means to avoid this new warning, because there are gazillions of
such files out there, and we cannot possibly annoy users who will
upgrade to Emacs 31 due to these files.

We should instead disable the warning when these files are loaded.
The warning is for Lisp programs written by users, not for snippets of
Lisp written by Emacs itself for its own consumption.

I'm therefore closing this non-bug.
