> +An endpoint MUST NOT discard its handshake keys until the TLS handshake is
+confirmed ({{handshake-confirmed}}).  An endpoint SHOULD discard its handshake
+keys as soon as it has confirmed the handshake.  Most applications protocols
+will send data after the handshake, generating acknowledgements and ensuring
+that both endpoints can 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.

+
+### Discarding 0-RTT Keys
+
+Clients SHOULD discard 0-RTT keys as soon as they install 1-RTT keys, since
+they have no use after that moment.
+
+Clients do not send 0-RTT packets after sending a 1-RTT

The idea here was to state a fact, with a reference to the normative text. I thought that was preferable to repeating the normative text.
