Seems very unlikely to work. Most metroidvania mechanics are not "useful", they're just "required" like barrier breakers or hazard resistances. Players don't actually care about having the latter. Taking away the ability open orange doors isn't really different from introducing new purple doors that you can't open. The tech that is useful, like dashes and double jumps, is really nice to have but not especially interesting to lose imo. If you "need" the dash then it's just a key. If you don't need the dash then losing it is just less satisfying movement.
