This issue hasn't gotten much attention in QUICv2: https://github.com/quicwg/quic-v2/issues/7
Basically, we could simply reassign the packet type codepoints in v2 to so that Initials are a codepoint other than 0b00. For example: Initial = 0b01 0-RTT = 0b10 Handshake = 0b11 Retry = 0b00 To the extent the purpose of v2 is grease stuff, this seems like a pretty simple and good thing to do. To the extent it's supposed to exercise version negotiation, this change is a needless distraction. Does the WG think this is worthwhile? I hope to issue the next draft with the provisional version number allocation, so this is the right time to make this sort of change. Martin
