Quite. Although out of the four, it's the one that looks the most different from the TOS original. Then again, TAS took even greater liberties. Who knows, perhaps the time-mangling doughnut regularly alters its surroundings?
I doubt there are many Guardians around. But there could be plenty of Preserver Obelisks, so that location need not be the one from "Paradise Syndrome", where the one Obelisk we saw was not at any shore and the planet having several would have complicated the plot. OTOH, while starbases are decidedly generic and underground refineries might be common, I don't see a reason not to believe in a direct connection there.
