As for the subject's question: I think it might be safe, but it probably
won't make a difference: combine-after-change-calls is ignored when
before-change-functions is non-nil.
Also, regarding interaction with non-CC-mode buffers: you might be able
to improve the efficiency of the code by executing the command of the
various cursors starting with the one closest to point-max and finishing
with the one closest to point-min.
For CC-mode buffers I have more trouble guessing if such an ordering
would also help, or would hurt, or make no difference.
