It's a very good and thorough analysis, pretty much every live action remake of everything falls into the same trap of cutting substance/context in favor of having "cool" fight/action scenes. Unless an adaptation is extremely faithful to the original it will devolve into what kind of cool visuals can we do and then the actual substance of why those things happen and the point the writer was trying to illustrate is lost.
Also very insidious for the show to not include Saka putting on the Kioshi warriors' costume because it would be seen as promoting drag/cross-dressing in kids media, that is one of the most memorable parts of that episode and it makes no sense not to include it other than to be as marketable as possible. Makes me wonder how the one piece live action will deal with it when they get to it, whether it's the director's choice in this adapation or something top down from the current netflix execs.
