I loved this puzzle (one of my favorite parts of BG3 so far). I would definitely like to see more of these. The bypass lever makes sense to an extent as being a DM I've seen "obvious" puzzles bring an adventure to a screeching halt for hours while people try to figure them out without continuous hints. Story wise it doesn't make sense as this door was meant to block passage to the Underdark's monstrosities...I guess unless you are an average rogue.
