I don’t know that they are but I could see how it “could” impact the story.
I’ve spent most my life working in food and beverage, if you asked me to make you a good drink I could come up with hundreds of recipes, if you said don’t use vodka because most drinks use vodka, still easy, if you said no vodka and it must have whiskey, still easy, if you said no vodka, must have whiskey, and has to have OJ also… still possible but getting a lot more difficult, if you said no vodka, must have whiskey, must have OJ, and must be red in color… I can make it but I doubt it’s going to taste very good. I don’t know if that’s what’s happening but I can absolutely see scenarios where the stories are suffering because the writers are being given specific criteria and they are making compromising changes to meet them.
One of the critiques I often see in Disney reviews is it feels like they were written by committee rather than with a unified story, that would make sense if a bunch of people were adding their own bits and pieces into the writers original concept.
