@martinduke It would be the same.

Assuming that the `minimal_initial_packet_size` used for client-sent packets are going to be at least 400 bytes, a server would always have room to send one full-size packet. Therefore, the server can send a Retry, or start immediately with sending the TLS handshake messages. The only difference is that when the server does the latter, it's initial send window will be 1 MTU rather than 3 MTU.
