Actually, most of these that don't involve new key and door types are possible to make by filling a one-way passage with doors and keys (Refresh Key, Exact Door, Starry/Forceful/Weak objects, Colorless doors, possibly more that I didn't read and possibly Partial Blast Doors as well.)
It would definitely be nice to see these implemented though.
That may seem true at first glance, but with door types, what happens once other mechanics get involved? Sure, you can recreate an Exact Door with a pretty simple contraption… until you want to make puzzles that involve using Master Keys to bypass Exact Doors, or cursing Exact Doors, or making copies of Exact Doors… you get the idea. A simple one-time check to make sure you have exactly a specific Key count isn’t hard, but when you actually want it to behave like a door - with everything that entails - suddenly it’s not so easy. (Refresh Keys don’t have this problem since they’re not doors, though, so they’re easily recreate-able)
