Which previous message?  I don't see reasons against such a guideline in 
your previous message sent to this list.

Just look at the entry for this change in NEWS.27 (and the 
read-char-from-minibuffer one), which does not explain how to revert it, 
unlike the three other entries in the "Minibuffer" section:

*** 'y-or-n-p' now uses the minibuffer to read 'y' or 'n' answer.

*** Some commands that previously used 'read-char-choice' now read a 
character using the minibuffer by 'read-char-from-minibuffer'.

It seems to me that the "Any change that matters to end-users should have 
an entry in etc/NEWS" rule in CONTRIBUTE, which is already applied 
successfully, is also a good way to distinguish changes that are 
potentially controversial from the others, hence the proposal above.
