Thank you for working through this with members of the design team and for
writing this up so nicely.  The PR looks great.

Hi everyone,
>
> The discard keys design team has reached consensus on how to move forward
> with discarding keys, and has produced a PR to modify the spec:
>
> https://github.com/quicwg/base-drafts/pull/2673
>
> In a nutshell, we leverage acknowledgments as an explicit signal that
> indicates that an endpoint is in a given state, and use that to allow the
> peer to make progress. We believe that this PR prevents the potential
> deadlocks discussed in issues #2214 and #2267.
>
> Please let us know your thoughts in response to this email.

> Thanks,
> David
