```suggestion
ApplicationData prevents a client from sending a packet on PTO where there is uncertainty about the ability of the server to acknowledge the packet. This can happen before a client confirms that the server is able to decrypt 0-RTT packets, and also at a server before it has the keys to process an acknowledgement.
