After discussion, Spencer's comment degenerated into "pick one".

I'm not speaking for others who replied/followed up on this, but I was
thinking that it would be possible to use fairly precise terms to describe
what the QUIC implementation was trying to do.

After reflecting on what other people said, I'm thinking that the precision
I was hoping for won't be helpful for passive observers, and (for extra
credit) would be even less helpful if/when we deploy
https://datatracker.ietf.org/doc/draft-ietf-quic-multipath/ and a passive
observer isn't seeing all of the paths in use. 😀

So I'm thinking that anything we agree on for this document may not survive
the use of QUIC for new applications.

Do The Right Thing, of course.

Best,

Spencer

p.s.  😈 I can't wait for the day someone uses QUIC datagrams for an
application that can rely on DCCP as its f******* protocol, and all the
network operators are still looking for TCP traffic - but let's not *even *go
there in this document! 😈
