That's entirely an RtConfig issue but it would make RPSL transitions
easier.  Handling multiple protocol versions is not trivial though.

No but they may need to be able to read new objects that others have
written to figure out what's going on.

I was kidding about writing code for RtConfig, but the point is that
keeping specification acheivable has always been an IETF goal.  In
this case we want to keep in mind the limited staff working on the
tools or we end up with nothing that works in a reasonable time.
