As stated above, I think option 1 is problematic in sense that the endpoint might not know which application protocol it is taking, though the error code being used is specific to the application protocol.

Even for Handshake packets it is hard to tell if the peer has learnt the application protocol in use, as CRYPTO frames and CONNECTION_CLOSE might get delivered out of order.
