I've been rotating the concept of a metroidvania-like game without ability upgrades and gating in my mind. If there was just an open world that pulled a BOTW and had 3 locations you had to go to before you can beat the game, would that still be fun and interesting? Would people play it expecting ability upgrades and then be disappointed? I'm trying to find examples of games like this, and Rain World is the closest I can think of, and there's a LOT more going on in that game.
