Yes.

So when a RP decodes it and fails, the expectation is that the RP will
immediately upgrade to a newer version of their RP software?

If a CA jumps to the new version 'too soon', the CA risks losing their
ability to inject VRPs into the routing systems of the RPs.

At what point can a CA know or expect that sufficient RPs in the field
are able to decode their objects if they choose to use the new version?

Kind regards,
