If the server sent something back encrypted with the initial server secret and verified by the client, then that would also work. But the QUIC TLS doc is hard to read. It is not very clear what kind of key is used in the servers initial response - is that already 1-RTT, or is there a first flight with initial keys. If it is the initial key, then the client can only verify the tag if the ODCID matches. If it is hashed into the 1-RTT context, it doesn't matter.

this makes little sense to me: what key is used after GetHandshake server side?
