For me, it's really when breaking down the value of what you get here that makes it so out of whack with anything else.
Look at the rancho del zolaco package for fantasmic package, you get a full dinner, beverage and a prime spot to sit (yes, I realize ground sitting is not ideal for some) during Fantasmic, a show that if you don't have a package you will have to stand in a non-Prime spot all for $35. You're getting about $20 worth of food, plus a seated spot for Fantasmic for about $15.
Compare that to this, where it doesn't even sound like a full dinner, plus you have to stand during the fireworks show, plus the fact that fireworks are designed to be watched from main street on the castle (though I do think Galaxy's edge offers a very fun alternative view and I'm glad they started pumping in star wars music). I'll be generous and value the small bites and drink at $25 since food items are pricier and a bit higher quality at Docking Bay 7 than some other QS locations. The souvenir mug value at $20 (but I personally have no use for this so that's a wasted item for me), which means the special standing viewing spot would be a $44 premium on top of all that. All for a fireworks show that someone could pretty easily get a good standing spot for free without much hassle.
So VS the fantasmic packages, this is just seems like an absolute terrible value proposition for anyone. At least I understand with WOC that some people do need to sit, so having the dessert party is a big help for those guests (though I do find the price on that a bit obscene for any else, given how easy it is to get a great spot for free from the virtual queue). Maybe I'm just more hung up on saving money than the average Disney guest, but it just feels like the math on some upcharges are not mathing, as the kids would say.
