Thank you for the instant feedback and clarification, which was not
clear from the online documentation.
For sure DNS over TLS is not a common fashion today and thus
forward-tls-upstream to selective servers is perhaps the current state
of affairs. I was thinking that once it gathers steam and ISPs and
perhaps even DNS root servers implement TLS than tls-upstream might
become prevalent. In which case it would be sort of a dilemma with the
current stub-tls-upstream implementation. But that is perhaps for the
