>From the [Discarding Handshake Keys Section](

> Most application protocols will send data after the handshake, resulting in acknowledgements that allow both endpoints to discard their handshake keys promptly. Endpoints that do not have reason to send immediately after completing the handshake MAY send ack-eliciting frames, such as PING, which will cause the handshake to be confirmed when they are acknowledged.

We could change this MAY to a SHOULD and it'll resolve this issue.
