From an implementation standpoint, I think I'd prefer to keep sslmode
independent from the new implicit-TLS setting, so that any existing
deployments can migrate to the new handshake without needing to change
their certificate setup. (That said, any sslmodes weaker than `require`
would be incompatible with the new setting.)
