No, we are not removing any commands from emacs-29 at this time.  If
you plan incompatible changes in duplicate-dwim in the future, I'm
prepared to consider changes to it to make those future changes less
incompatible, but I won't agree to removing it.  This discussion
should have happened a year ago, and now it's too late for such
proposals.  Sorry.
