I consider the whole version alias mechanism must be strictly optional for client and server. If it is used, it may provide an early signal for version negotiation tapering.
The server MUST NOT assume that the client uses any of the version aliases, but the server MUST accept all version aliases it presented the client with during their lifetime unless it also stops supporting the aliased QUIC version (thanks @martinthomson ).
