Subject: [Scone] New draft: scone-echo

Hello SCONE,

I've published a new internet-draft:
https://datatracker.ietf.org/doc/draft-duke-scone-scone-echo/

Basically, it's a QUIC extension to report bandwidth advice back to the SCONE sender in a QUIC frame. We have some edge cases where the sender can do useful things with this advice but the receiving application is unable to cooperate. See the intro for a somewhat more thorough discussion of that.

The relevant chairs/AD agreed this should sit in SCONE and not QUICWG, although it may need a recharter.

Anyway, if this interests you, take a look and file issues in the github<https://github.com/martinduke/scone-echo>.

Thanks,
Martin
