@RyanAtGoogle
> it sounds like you are recommending something like the previous RETIRE_KEYS proposal?

That might be the case (honestly I do not remember the details of the RETIRES_KEYS proposal), though I think I'm inclined to suggesting using a continuous signal (i.e., a Key Update or burning an unused header bit). The reasons being i) using a continuous signal allows us to abandon the Handshake keys earlier ii) we do not need to define a new signal that needs to be retransmitted in the transport draft, or rely on a particular behavior defined in the recovery draft that is not generally considered as necessary for a recovery logic (i.e. PTO "MUST" trigger a PING when there is no data to send).
