I disagree, for reasons given before:

1. Anyone who wants it can bind it.  (I do.)

2. It has no meaning for many modes.  By its
   very nature it is essentially mode-specific.

3. Modes where it is useful typically already
   bind it.  And they bind it to a key that
   makes sense for that particular mode.
   You just need to use `C-h m' to find out
   what the key is.

4. Given #3, if you add a global binding for
   it then there's not much point in those
   mode-specific bindings.

5. Emacs has been fine for 35+ years without
   any global binding for it.  The "Founders"
   knew what they were doing in this regard.
   (Perhaps they were thinking of some of this
   list.)

6. Emacs should impose a moratorium on itself
   NOW, to stop binding keys by default.  Just
   say NO.

   Seriously.

   The few keys that still have no default
   global bindings should be left as is, in
   general - left for users and 3rd-party code.

7. IF many users start using some binding over
   a period of years THEN Emacs can consider
   giving it a default binding.  Don't be
   prematurely "optimizing" UI in this way for
   people when there has been no popular
   request for it.

8. YAGNI.

One opinion.
