Not really. Roll back the world to SSLv3 being the latest:

I would be proposing this:
sslversions "2 3"

Then the IETF changes the name to TLS and restarts the numbering. That's
trivial to address:
sslversions "2 3 tls1"

So if TLS gets renamed to XYZ, it just becomes:
tlsversions "1.2 1.3 xyz1"
and make
xyzversions an alias for tlsversions.

This is really small potatoes. If you want it to be like this, I don't care:
tlsversions "tls1.2 tls1.3"

But we're still putting tls in the option name, so is that a problem?
