@kazuho for you problem with (a) isn't that just a general problem with having multiple paths and then getting a NEW_CONNECTION_ID with RPT for all previous CIDs? You end up in a scenario where you only have 1 CID (the new one) and multiple paths that just had all their CIDs retired. If you can get away with using that one CID for the active path, you can still make forward progress. If not, the connection dies.
