@janaiyengar It is the most straightforward way to send PTO and I see no downside, so yes.

That said, I know that many of our mechanisms (e.g. discarding keys) bake in assumptions about the handshake and who sends what and when, so maybe we should examine the implications of, for example, a client sending a Handshake PING before it gets any Handshake packets from the server.
