No, an intermediary is not the same as a Man-in-the-Middle. If you use the term MITM to me, I will immediately interpret that as a description of an attack because that is what the established use as a term of art defines it to be.
You should not be using MITM for any situation where a positive or even a neutral disposition is intended. It is unclear at best, I regard it as wrong.
A DNS resolver is a point at which a MITM attack might be staged but it is not a MITM attack of itself. And the notion that resolvers are mere relays is actually one that I think is wrong and has held back development of DNS. The client-resolver protocol need not be the same as the resolver-authoritative. These are entirely different applications that should not have been confused in the first place and we are only recently managing to unconfuse. The no-DNS and DoH work are examples showing why the resolver-authoritative protocol is not the most effective.
If I talk about an Email relay being a MITM then I am saying that changing my character set, wrapping lines and all the really obnoxious behavior they routinely engage in are attacks.
Of course on the gender neutral side, MITM attacks are traditionally performed by Eve. And historically, many of the intercept operators on the allied side were women. It was one of the few field combat roles they were permitted.
