From a user perspective, this seems like a decent trade-off. For me, not
being able to use the previous behavior would mean that I'd have to stop
testing Git releases until Emacs 29 is released.

Not having such a knob would also prevent any user who is for some
reason stuck on an older version of Gtk to upgrade Emacs.
