I agree with you that this is already happening in the vast majority of 
cases, so why would it be problematic to make this a rule, that in 
principle any change to Emacs' behavior should provide a way to re-enable 
the old behavior?  IIUC that's all Richard wants.  Of course that rule 
would not apply to bugfixes, and exceptions would be possible with the 
explicit approval of a maintainer.
