> I am not sure why this affects load balancing at all. The CID is part of the invariants, so LBs should be able to read and parse the CID without regard for the other versions.

If the pool of servers handling one version is different from another pool, for example in a blue/green deployment. Since client decides ODCID, you have nothing but the version to route on. You could, however, use a retry get a new DCID so traffic will route correctly.
