QUIC: "handshake_timeout" configuration parameter. Previously QUIC did not have such parameter and handshake duration was controlled by HTTP/3. However that required creating and storing HTTP/3 session on first client datagram. Apparently there's no convenient way to store the session object until QUIC handshake is complete. In the followup patches session creation will be postponed to init() callback.
