This gets touched on now & then, & probably had it's own thread in the past, but it's interesting to me that while it was forbidden to feature 23rd century Earth on TOS, the movies featured Earth in all the films, in some minor amount
Some folks don't care much for it, given how the show is meant to be about exploring the stars, & I can relate to that. In a slightly different way, that was my major initial gripe with DS9, (Not a trek throughout the stars) but I don't think featuring Earth was all that bad, not for the film format anyway, which was more character driven than the show's story driven format. It's pretty important in character stories to have roots for everyone.
The ship also needs a launching point, for the in-universe logic. Basically TOS is about a five year exploration mission, but by the time the movies begin, that mission is long over for this crew, and we're in the wake of how their lives have developed, thereafter. Even TMP has them all scattered to the wind at the beginning. So essentially Roddenberry himself gave the go ahead to break his own TOS bible rule & feature 23rd century Earth. (Probably because they finally had the money to do it right)
Besides, where else would all these people/officers (Most of whom are from Earth, where Starfleet is headquartered) end up reuniting, to take on each of these subsequent missions, featured in the films? 6, 5, 3, 2, & 1 all have to begin somewhere, & 4 kind of needed to send them back there in the aftermath of what they'd done
The only alternative to having them back on Earth to some degree, now & then, is to still have them on the same ship out there, with the same crew, still having been on assignment all this time without any significant change, & how feasible is that, after all this time had passed?
