A certain amount of experimentation is necessary in order to evolve the franchise and to keep it relevant for today's audiences.
Deep Space Nine was an experiment ("How can this be Star Trek? It doesn't go anywhere! It's too dark!")
Lower Decks was an experiment ("This isn't Star Trek! It's too much like Rick and Morty!")
Star Trek: Picard was definitely an experiment. It was the first Star Trek show to be centered around a person as opposed to a ship.
The question is: Would more than 400,000 people be interested in revisiting Archer?
I think it's interesting that most of the
Trek shows of late have been experimental in that they didn't follow the traditional format of the bridge crew being the main characters. I suppose
Disco and
Picard ended up being more traditional but
SNW is the only one that's been 'classic format
Trek' from the get-go and I don't think any shows suffered due to format shakeups. Indeed, one of the criticisms of
Voyager and
Enterprise was that they felt similar and indeed that
Voyager didn't really make more of the impact of the arduous journey back home (which RDM would clearly fully deep dive on in
Battlestar).
I think having different types of shows also makes sense if there are multiple shows concurrently, although I do wonder if starting fresh with a new 32nd Century Enterprise as a clear 'main' show may help attract new viewers.
In terms of an Archer show, I'd love one! However, I agree it probably wouldn't have broad appeal. I mean,
Enterprise didn't seem to really have an impact in wider pop culture the way other series did. I mean, I knew sci-fi fans (and indeed
Trek fans!) who didn't watch it.
