I strongly second not breaking backwards compatibility and
interoperability, especially for persistent artifacts, unless there is a
*REALLY* good reason. A potential unintended side effect of such breakages
is that it slows down adoption of the new version.

I think it's better not to introduce a new opcode, for the reason you
stated -- you don't want your pickles to be unreadable by older Python
versions, if you can help it.
