My main concern with districts is the illusion of choice. You are always going to want to put your civ specific cultural buildings in the same district. You could put them in separate districts, but why would you? Combining them gives you that unique district. And I suspect the same is true for other buildings as well. The only option perhaps, is opportunity cost. In that you may be waiting for tech to unlock before you can place a building, so you have to leave a building slot empty and eat up another tile for another urban district to place another building and then later fill in those empty slots for the adjacency bonuses. We'll see how that goes.
I'm guessing because of the ages mechanic, that we can overwrite buildings in districts. So that shouldn't be an issue. And I'm guessing districts can be taken out even during the age transition.
