In the editor's draft, PTO replaces the handshake timer, TLP and RTO.  In the current editor's draft, it's armed until the client has 1-RTT keys.  So the client must retransmit something in Initial or Handshake encryption levels to move the handshake along.

Given that, I'm unclear on what the issue is?
