/* RFC 9000
* 4.9.3. Discarding 0-RTT Keys 0-RTT and 1-RTT packets share the same
* packet number space, and clients do not send 0-RTT packets after
* sending a 1-RTT packet (Section 5.6).
*
* Therefore, a client SHOULD discard 0-RTT keys as soon as it installs
* 1-RTT keys as they have no use after that moment.
