Review comment:
With IBP 3.0, the message format version will always be 3.0 and the
record version will always be 2, so it works as you said. Even though it's a
bit roundabout. I could have the IBP check here, but it seems to spread the
logic into more places. I could add a comment perhaps. Thoughts?
