The problem with that scene from a scientific perspective is that it’s strongly implied that a Hyperdrive is literally able to accelerate objects up to and past the speed of light, instead of opening a tunnel into another dimension.

No, there’s normal speed driven by normal engines with normal physical limits, and there’s lightspeed for which you need a hyperdrive. The former is normal motion in real space, while lightspeed is achieved in another dimension called hyperspace.
I’ve only read the last few pages of the thread, so my apologies if this has been mentioned already, but on the topic of whether hyperspace involves simply travelling really quickly or entering another dimension, ANH would seem to establish that it’s the former, since one is still at risk of interacting with physical objects in the universe. As Han says, “Traveling through hyperspace ain’t like dusting crops, boy! Without precise calculations we could fly right through a star or bounce too close to a supernova and that’d end your trip real quick, wouldn’t it?”
Actually it doesn’t necessarily establish that it’s the former, since Han’s remarks also apply, if you only consider the exit point of hyperspace travel in another dimension. Without precise calculations the exit point might be too close to or inside a star or supernova.
The old canon established that planets and stars cast ‘mass shadows’ in Hyperspace that must be avoided. This handily explained why ships going at relativistic speeds don’t get shredded by random floating particles and debris en route - the debris doesn’t have enough gravity to affect Hyperspace.

Regarding the hyperspace kamikaze: I didn’t have a problem with the physics of the stunt, and in isolation it’s undeniably a cool scene. I just don’t think it fits with overall SW worldbuilding. In a realm where hyperspace travel has existed for at least “a thousand generations” (Ben Kenobi, Ep4) - or more, if you count references in the EU - somebody, somewhere, at some point, should have had the lightbulb of weaponizing a hyperdrive. Not even necessarily a ramming maneuver, but perhaps, say, an “ISBM” - interstellar ballistic missle - that enters hyperspace, comes out wherever it’s programmed to, and devastates the target.
Even within the context of TLJ, if Holdo or some other character had voiced this idea, someone else could have briefly referenced why such weapons aren’t used (e.g., too much unavoidable or unpredictable collateral damage). That would have made it make sense. Ah, but Ruin Johnson wasn’t interested in well-thought-out storytelling.
In any case, I’m wondering what to do about this scene in my eventual reedit (TFA and TLJ will be combined). I think that, as it stands, it’s problematic in the larger SW context.
The idea I’m leaning towards is to somehow imply that the Hyperspace Tracker on the Supremacy causes a part of the ship to be constantly within the Hyperspacial dimension, and this allows the Raddus to ram it, for the two ships essentially collide in Hyperspace. For if the Supremacy was completely located in real space, its relatively small gravitational mass would have little effect on the Raddus, and they would pass like ships in the night.
The biggest benefit of such a change would be that the First Order is undone by their own supposedly superior technology, a very Star Wars theme.
