Bernard created https://github.com/mengelbart/rtp-over-quic-draft/issues/53
yesterday, which is a cut-and-paste of your review, so I think we're
synchronizing well.

Mathis and Joerg added me to the repo, but this is still a draft they have
responsibility for, so I should let you coordinate with them, and I'll do
my best not to step on anyone else's toes, or proposed changes.

And thank you for your help. I do feel that we might be breaking a logjam,
after today's virtual interim meeting.

Best,

Spencer
