Then please document that as part of fixing the issue on master, so
that it will be documented from now on.

Given all the downsides, I'm okay with reverting the fix on emacs-29.

Please in the future make it clear when you object to a patch, and
describe its aspects to which you object.  Presenting an alternative
one is not enough to convey that.  If I realized at the time that you
are against it, especially if you'd explain why, I would have avoided
wasting my time on installing it, and that would have saved us some
time discussing the issue later -- a net win for everyone.

Thanks.
