It’s less to do with Kathleen Kennedy and more with the markets. Kennedy is not some evil boogeyman that hates Star Wars, let’s not entertain the sexist bullshit against her.

Disney just shifted their entire market strategy to focus on Disney+. When physical media was still the focus for post-theatrical release, it made sense to entice people into re-purchasing, so they added content. Disney is famous for artificially controlling supply and demand with physical media, placing films in the “vault” and re-releasing them with bonus content years later.

Such a strategy doesn’t make sense anymore, people are either subscribed or not. Deleted scenes won’t be enough to get new subscribers, and would only increase piracy (which decreases subscribers). Alternative cuts and new narrative content does draw people in.

That’s why Justice League has a ton of money being spent on it: they’re treating it like a new Max Original series. Compare this to Dawn of Justice, where the alternative cut already existed and could entice new purchases, or Suicide Squad, which has a cut that’s unfinished similar to Justice League but without the ability to draw new subscribers into HBO Max.

With Star Wars, releasing the Theatrical Original Trilogy in 4K would draw in new subscribers, just as new original content like The Mandalorian, The Bad Batch, and other shows are. Deleted scenes aren’t quite enough, and recutting The Rise of Skywalker would be a much larger task and would require Abrams’ collaboration. The cost-to-subscribers ratio wouldn’t be profitable enough for them, even if they could get Abrams to admit his fuckup and come try to fix it.
