For most of Star Trek’s history, the Prime timeline holds together no matter what happens to it.
I respectfully disagree.
James Kirk of the united earth space probe agency or whatevs sends his regards to the united federation of planets 🙃
Later in Disco we see… many anachronisms, which makes it hard to write of earlier inconsistencies as just errata.
My own conclusion is that star trek is like a jigsaw puzzle both with some pieces missing and some pieces from other puzzles entirely.
Edit: as a counter point, I would say that statement is true of other (smaller) franchises, like planet of the apes.
