I understand, but the changes are non-trivial, and I cannot see any
urgency to doing that on emacs-29. We lived with the current
implementation for a year.

I don't object to installing your changes, I just don't want to risk
any more unnecessary breakage on the release branch. My point about
duplicate-dwim is that it was added at our initiative, so extending it
could wait till Emacs 30.
