Not any more than it’s fair to assume that, by showing the Barge of the Dead, or the Miranda-class, or the Oberth-class, or the Galaxy-class, or the proto-Klingons, that VOY: “Barge of the Dead”, ST II, ST III, TNG or TNG: “Genesis” took place in a reality with different class ships or people.

The Mirror Universe question is a separate one, to which there really is no good answer because we’ve only seen crossovers from the Prime Universe to its Mirror Universe counterpart. A bigger question is whether or not the Mirror Universe we saw in PRO: “Broken Mirror” is the same Mirror Universe we see in DS9 because there the Terran Empire seems to exist again.

Thank you for noticing the typo!

Yes, the XCV-330 was an early Matt Jeffries concept for the Enterprise back in 1964. That’s why it turned up in TMP as a painting.
