There are two problems with C-?:

* It requires two shift keys, so it is inconvenient.
(The bindings for undo ensure it can be typed with just one
shift key on all usual terminals.)

* It does not exist at all on ttys.  (I don't know whether we can
change that on Linux consoles.)

Whether constitutes a problem for the undo-redo feature depends on the
precise meanings of the two commands.  I don't know those details
so I can't judge.

M-_ is likewise inconvenient because of the need for two shift keys.

Defining these keys in addition to the existing binding for 'undo'
can't do direct harm.  But it may disappoint the users you're trying
to help.
