- We won't want to use named policies, as they can be updated in the future, so prefer a numbered policy for stability
- I don't think it's correct to have both of these mapping to the same policy. Generally the policy should have the mapped options as the highest preference. When an s2n-tls client is handshaking with an s2n-tls server, it can't negotiated both of these.

Both points make sense. None of the dates-only policies preferred both PQ kex and AES 256, so I used PQ-TLS-1-2-2024-10-09. I don't expect that policy to change through time.
