The code which supports PREV-CHUNK is already in Emacs, so the
question IMO is "why remove it"?  If we want to try to get this into
Emacs 26, we should strive to make the code changes minimal, ideally
zero.  Once all we are left with are documentation changes, the
feature can land on emacs-26 right now.

So I think it's worth our while to take a very good look at the
proposed changes and think hard whether we absolutely must make those
changes, and why.
