While reading https://quicwg.org/base-drafts/draft-ietf-quic-transport.html#rfc.section.14, one can read that any Initial packet from client and server MUST be padded to at least 1200 bytes.

> The payload of a UDP datagram carrying the Initial packet MUST be expanded to at least 1200 bytes, by adding PADDING frames to the Initial packet and/or by combining the Initial packet with a 0-RTT packet (see Section 12.2).

My understanding is that only client first Initial packet MUST be 1200 bytes.  If it is correct, it would be nice to explicitly state that so.
