Using different message IDs is bad.
Usenet already has a header for this: Message ID.

But if Google ever moves away from maintaining a Usenet archive, then
any links involving Google IDs will be broken. This happened with
DejaNews and will happen with links to old URLs with the GG1 (Google
Groups 1) system (unless they maintain continuity). Even then, all was
not lost because you could extract the Usenet message ID from the URL.
It looks like you can't do this with the new GG2 message references.

I would also *always* add the Usenet message ID.
This timeproofs it against any future changes.
