The opposition mostly comes from the fact that you appear to to proposing an across-the-board nerf without anything in return, one that affects us too, when we might not necessarily have wanted this.
Right now, if you don't like the room, you are free to not search for it.
If we do like it and your idea passes, too bad; the bonus is nerfed and taken away, and we're not free to do anything to get it back.
If you feel like you have to find it, currently, then think about all the reasons why. List all the reasons why "just skip it, then" isn't a good option for you. Now, take that list, ignore it, and skip the room anyway. "But the item purchase on the next floor-" Yeah, now you won't be able to afford it. Sucks, doesn't it? That is what you want the rest of us to feel from now on, every time, with no way back.
That is what your idea would make less of our run.
