Slingshot maneuver is from "Tomorrow is Yesterday", they never used the cold intermix means of time travel again. (Although there was a fanon "time ship" from the 80s that did.)
This is another example of TOS so often steering clear of presenting anything as totally new and unprecedented. Clever androids? Mind-eating, space-dwelling,mind-controlling lifeforms? Duplicate Earh cultures? Time travel? Weird and challenging, but never quite unfathomable or previously unknown. Which is why "Balance of Terror" stands out like a sore middle finger when it tries to claim that something as mundane as invisibility ought to be surprising or indeed merely theoretical.

It doesn't have to be a continuation of TCW. It would just be what happened in the 23rd century as part of the same TCW. We only saw the 22nd century (and other) incursions/results Archer and co. witnessed.
Canonically, Future Guy's faction couldn't travel backwards in time - only send messages backwards. So even if the probe went into the future at roughly the same time period, it couldn't be as a result of Future Guy's faction, but some other player.
I seem to remember Daniels mentioned other factions, but of course he never went into great detail for reasons.
The TCW...yeah...let’s return to a barely thought through plot device from a Star Trek series that barely anyone watched and was the first ST show to be cancelled. That’s a great way to tell a story.
Ah, I see my error. Let me rephrase: ENT was the first Star Trek show to be cancelled since TOS. Better?
Can't there be new drama/new storytelling using Talosians? I mean, other Star Trek series had reused aliens on multiple occasions and still told new stories with those "repeating" aliens. Why wouldn't DIS be able to tell a generally new story using Talosians? Granted, I'm sure the story will have something to do with Talosians' mind control abilities, but that's more of a "premise" thing than a plot or storyline.
As I've noted numerous times in the past, in different ways TNG, VOY, and ENT all tried to mix up the formula by showcasing different races. TNG in early years attempted to push up the Ferengi as baddies, which...didn't go well...and ended up partially returning to the Klingons and the Romulans. VOY went to the Delta Quadrant - an entirely new part of the galaxy - but attempts to come up with new antagonists like the Kazon were mocked. Ultimately they turned to the Borg. And ENT tried to introduce new races like the Suliban and the Xindi, but ultimately went fanwank in the last season. Face it, Trek fans don't want "new worlds and new civilizations." They want to boldly go where we have gone before.
