I already hummed in the room, but I think it should stay as TLS 1.3. Either of TLS 2 or TLS 4 makes the SSL/TLS silliness worse. One matches SSL 2.0 and the other just makes all this weirder. (Do we really want 2.0 < 3.0 < 1.0 < 1.1 < 1.2 < 4?)
TLS 1.3 is the natural next number and doesn't make anything worse. Let's just use it.
