*Dear QUIC WG,On behalf of the Stream 0 Design Team, I am pleased to report
that we have consensus on a proposed approach to share with the WG. The
DT's proposal will make QUIC and TLS work closer together and incorporates
ideas from DTLS, but it does not use the DTLS protocol itself. The DT
believes this solves the important open Stream 0 issues. The proposal will
be a bit more invasive in TLS, but we believe it is the right long-term
direction and several TLS stacks (BoringSSL, PicoTLS, NSS, and Mint) are
willing and able to do the work necessary. A number of stacks are currently
working on implementations of this new approach, which we hope to have in
time for the Interim meeting.A design document describing the overall
approach can be found
PR making the changes to the QUIC documents can be found
<>A few design details did not
have clear consensus, but it was felt it would be better to discuss those
in the wider WG than delay the design team.  A consistent choice was made
in the PR and these issues are mentioned in Appendix B of the design doc.As
always, comments and questions welcome. That said, this is a big PR and we
recognize that some editorial work is going to be needed before merging. In
the interest of letting people follow along, and to keep github from
falling over, we ask people to keep discussion on the mailing list and
refrain from making PR comments.See you in Kista!*
Ian and Eric
