Personally, I use `C-s C-y' as a prefix key for
several different yank commands.  So that's another
reason I'm not in favor of moving the longstanding
`C-s M-y' behavior to `C-s C-y'.

(And with luck Emacs itself might someday want to
use `C-s C-y' as a prefix key for yank commands.)

For users, reverting this change "would be a step
backwards" only in the sense of reverting an
unsolicited step backward.
