"hyperspace tracking" is one of many ways you could write in a way for the empire to get the rebellion "on a string"
like, you could introduce a political dimension to the film about inserting agents in all corners of the galaxy as whistleblowers or whatever
hyperspace tracking breaks, barring some arbitrary after-the-fact addendums to clarify maybe devastating hyperspace weapons haven't been in use throughout galactic history for some reason maybe being some size limit to the effectiveness like maybe smaller ships not actually causing damage to anything but themselves etc, hyperspace tracking doesn't make sense considering every battle we've ever seen and supposedly changes the way everything happens from on out
THE FORCE IS FEMALE
i've actually been thinking lately that since if snoke's corpse was a projection, since it was established he could do things like bridge minds between stars and projection is a thing now because luke, perhaps he is still alive
and if he is still alive, one crazy "twist" that i would actually find compelling would be snoke turning out to literally being the force, undermining the whole concept of the force creating a unique new dilemma
a neat way to create a narrative about the concept of a malevolent God
but they're never going to do that
