I think people don’t really care about deleted scenes anymore outside of the fan-edit community. The large preponderance of them aren’t very interesting, and I wouldn’t be surprised if part of why there aren’t any deleted scenes is because whatever there is doesn’t really merit much attention.

That or stuff like spider-baby-head thing is just too weird for them to plop on a disc with not much context.

Of course, to provide the context you basically have to go all the way into the story of how and why that whole Mustafar scene is made more or less entirely pointless in the final edit, and how it was once built out of Trevorrow’s earlier Duel of the Fates ideas, and then you have to get into why Trevorrow got fired, and THERE I’ll fall in line with those who have noted Disney’s ownership of Lucasfilm isn’t very interested in the sorts of warts ‘n’ all behind-the-scenes stuff that independent Lucasfilm didn’t mind indulging - even WITH Lucas’ habitual retconning of history factoring in.

I’ll never understand why they didn’t just cut the whole Mustafar sequence out of the final edit. It’s beyond pointless and you learn nothing from its staying in that you dont learn contextually from the movie later. It’s just a confused mess of jumbled imagery that doesn’t tell a story or help the larger story make any more sense once its done. I mean, I understand why they did it, its just that the reasoning is so half-assed at best and bad at worst that it doesn’t make sense to me (especially since they were already in “Get it under 2:30 at all costs” mode, which was also a dumb decision).
