    Indeed:  (defalias 'set-variable 'customize-set-variable)

    Note that if you mean this literally, this is a non-trivial change in
    as far as prefix arguments are concerned.  Right now, C-u set-variable
    will set the buffer-local value.

Yes, we would want to add a similar C-u feature to customize-set-variable
before doing this.
