Yeah, that's what we should do and I would vote for doing nothing as
long as we are not sure how the TLS is shaped at the end, as we could as
well be able to use only be-tls-end-point so -PLUS can be advertised.
From a technical point of view, the decision-making can happen with
Port->ssl->version by looking for TLS1_3_VERSION which is new as of
OpenSSL 1.1.1 so that's very fresh (1.1.1 beta 5 is out as of today).
