When there is nothing to send today, the text says you can send a PADDING only packet.

These packets will be removed from flight when Initial keys are dropped, but it may never be acknowledged, which loses some congestion control signal, including RTT measurements.

For PTO, we decided you always send a PING if PTO expires and there's nothing to send.  It seems like we should say the same for the handshake case now that it's part of PTO?

This came from Ryan's comment on #2806
