I personally dismiss These are the Voyages. The real finale and the real end to the on-screen tale of Enterprise is Terra Prime. TATV is nothing more than a TNG holo-deck episode, with ENT characters in the holo-deck. Those were not the real characters, and without even reading the post-ENT novels, who is to say that the 200 year old records of Trip's death, let alone the rest of the depictions of the NX 01 crew, are even accurate by TNG's era? There were minute differences in the uniforms (name tags), T'Pols hair was different, Slight differences on the bridge, etc. The fact that no one was all that upset with Trip's death was out of character, and also we never actually see Trip die, anyway. One scene he is going into the medical chamber alive, it cuts to commercial break, then the next scene is Tpol folding Trip's clothes and the dialogue is he is dead. Way I see it is if we don't see it on screen, it didn't happen.
