That's not what I propose. I propose we drop support for the libraries that do
not offer TLS 1.3 for curl (fifteen months into the future).

They could still negotiate older versions.

QUIC uses TLS 1.3. So by definition, all TLS libraries that support QUIC also
support TLS 1.3 and thus would not be affected by my proposal.
