The problem is, as it stands, the end user DOES have to care about if somethings Nanite or not. Mesh paint does not work with Nanite, numerous of Fortnite’s own assets look completely different and stylistically clash between Nanite and non-Nanite, certain materials may not work as expected on Nanite, the list goes on and on, until the day comes where full Nanite and non-Nanite feature parity is achieved, I do not see a world where this is removed from the engine itself, when the time comes that it is however, I feel its a safe assumption that feature parity would have been achieved, and at that point the removal would not matter for Creators.
