Yes, the 0x40 bit is always 0, because we never deployed multipath.

There's been quite a bit of discussion about the spin bit, including a new draft sent out today: 
https://datatracker.ietf.org/doc/html/draft-trammell-quic-spin-00

The current proposal makes the type shorter, but the nonce bit would still always be 1 in the above proposal, so as long as no other bits are used for anything, we should still be able to use the plan of looking at the first bit or the nonce bit to detect IETF QUIC?

But as Marten says, this PR definitely makes things more complex than I originally thought, particularly in light of other potential header changes.
