That is not comparable: C-u is the universal-argument key, and it's
sole purpose in life is to serve as a prefix key to extend the
behavior of the others key sequences.

However C-y is not a prefix key, and the proposed behavior of M-y is
simple, well defined, and doesn't need to be extended by C-y, because
such pretended extension will be already bound to another key (M-p),
which is the natural choice.

With the "bloated" version of M-y, users would not be able to browse
the kill-ring in the minibuffer just after yanking the top entry with
C-y.  And why? Because of an unnecessary complexity in M-y.

Please, let's not make that mistake.
