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.
