Interesting speculations. In my mind this all goes back to the mindset of whether you’re open to new possibilities or not. Hyperspace has been ill-defined enough in this franchise for there to be a sort of gap in possibilities where this can happen. The fact that it’s never happened before doesn’t mean that makes this impossible, it just tells you what is possible with this power and what isn’t. So while before we had no idea if hyperspace could be weaponized, now we know it can be effective is specific situations, but presumably not a course of action worth exploring in other situations.
From my perspective, it’s not hard to see how the logic of this works. Honestly, it seems to me like you have to bend over backwards to try to be bothered be it, but if people want to, that’s up to them I suppose.
(as for Holdo’s fate, as I’ve said I’m pretty sure what happened here was the Raddus impacted with the Supremacy before it enter hyperspace.)
It depends. I like internal consistency in my worlds. Harry Potter and the Cursed
Child’s handling of time travel, as an example, goes against what prior books established, and it irks me to no end. Meanwhile, for Star Wars and hyperspace ramming, it’s entirely out of the blue, with nothing before it to compare to. I can easily see why it’s divisive. It has no rules to compare to; all we have to go by is what we’ve seen on screen (really effective), and the fact that it’s never been attempted before. Most likely it’s unreliable for some reason, but why? We can speculate all we want, but we don’t have enough information to work with.
TLJ doesn’t need to tell us everything, it can tell its own thing. Really, it has more ramifications for other works in the franchise, which are shackled with treating the world like a real place with some kind of rules governing it.
