Yes.

It would break existing code. BTW "check for a valid buffer position"
won't work with copy-marker for other reasons (e.g. (copy-marker 0)
returns a marker pointing to (point-min), even though 0 is not a valid
position).
I have no idea why you think copy-marker might be a good way to solve
your problem, but the evidence seems to suggest you should try
something else.
