> In reviewing this, I think we've messed up badly. We currently only mandate the use of a new connection ID for the initiator of a migration. A peer that responds to a connection migration has to change a connection ID if the initiator changed their connection ID.

This has been discussed at length and while I tend to agree that this is not a good design, I believe things ended up as they are due to concerns about endless CID change loops. I think that can be prevented without too much complexity, but that argument was one of the drivers, as I recall.
