How many people have shipped version negotiation and v2 already? I assume that implementations are using the codepoints for the transport parameter in the draft (0xFF73DB), but the drafts says this:
> When this document is approved, it will request permanent allocation of a > codepoint in the 0-63 range to replace the provisional codepoint described > above. IANA are about to make that new allocation, but that might not do good things for interoperability. We're not changing the v2 version number and v2 *requires* the use of this transport parameter: https://quicwg.org/quic-v2/draft-ietf-quic-v2.html#section-4-2 Consequently, an implementation that uses the current transport parameter codepoint will not interoperate successfully with an implementation that uses any new transport parameter codepoint. So, we either allocate a new codepoint for both, or we keep the existing ones. Which do people prefer? Or, am I wrong about this?
