Everything in Epcot Center (Save for Imagination) was about the future of each topic area. "How do we make this better for the future" If there is something in the Way of Water that talks about how water will drive the future in some way (growth, human advancement, etc) then I will gladly eat humble pie. Epcot Center specifically was mostly about achieving human growth through technology advancement. Remember, as Walt said
"EPCOT will take its cue from the new ideas and new technologies that are now emerging from the creative centers of American industry. It will be a community of tomorrow that will never be completed, but will always be introducing and testing and demonstrating new materials and systems. And EPCOT will always be a showcase to the world for the ingenuity and imagination of American free enterprise." I know that this is no longer called Future World, however, if I may be so bold, the people that feel that this does not belong in Epcot expect the things that are put in Epcot to follow the original vision for Epcot Center which ended up becoming a test bed approach for the original E.P.C.O.T. a fact that the designers of transformation really pushed hard to have us believe. So, under that premise, the Moana walk through does not belong in Epcot. Does it ultimately belong in what the transformation ended up becoming? Of course, they could put anything in Epcot at this point.
BTW: if I look at this photo and were a novice to Disney Parks, I'd truly think I was looking at a photo from Animal Kingdom and not at all Epcot! :
