One nit on your first point:
> We are creating another set of resumption information that needs to be retained by the client (we already have NEW_TOKEN token, TLS session ticket, and optionally H3 SETTINGS).

Aren't clients required to store transport parameters when doing resumption already, so this is moving it from one place they store to another?

There are servers that will want to use NEW_TOKEN and not do version greasing, so I believe this really should be optional if you put it into NEW_TOKEN, just like it would be in transport params.

You are receiving this because you are subscribed to this thread.
