This doesn't look right

```
In using TLS, the central key schedule of TLS is used.  As a result of the TLS
handshake messages being integrated into the calculation of secrets, the
inclusion of the QUIC transport parameters extension ensures that handshake and
1-RTT keys are not the same as those that might be produced by a server running
TLS over TCP.  However, 0-RTT keys only include the ClientHello message and
might therefore use the same secrets.  To avoid the possibility of
cross-protocol key synchronization, additional measures are provided to improve
key separation.
```

The CH will also contain the QUIC transport parameters, so why aren't those keys different
