 Handshake or 1-RTT packets.
 
+When a server receives duplicate CRYPTO data in an Initial packet after sending
+its Initial flight, it can assume the client did not receive all Initial CRYPTO
+data. To speed handshake completion, it SHOULD retransmit all unacknowledged
+Initial CRYPTO data subject to the path validation limits.  After doing so,
+the PTO is re-armed.

The server can't send if it's limited by the amplification factor, but the PTO can be armed otherwise.
