I did a [write-up about this](https://www.ietf.org/mail-archive/web/quic/current/msg02009.html) some time ago. I think this change will make it easier to differentiate between gQUIC and QUIC.  Types 0x1F, 0x1E, and 0x1D would give us the following gQUIC interpretations, in order:

1. 2-byte packet number; connection ID, nonce, public reset, version bits set.
1. 2-byte packet number; connection ID, nonce, public reset bits set.
1. 2-byte packet number; connection ID, nonce, version bits set.

gQUIC public resets do not have two-byte packet numbers.  Likewise, gQUIC version negotiation packets are unlikely to have two-byte packet numbers.
