I see all the points and they are all worthy. I'm still sticking to my original statement.
I've noticed, since I went back to using just on reverb, that my mixes seem less cluttered and much more open. Or, I just started mixing better. One space can only have one reaction or color. IMO, putting many colors cause inconsistencies that muddy up the mix.
Of course, everything is subjective so does it really matter? You have to do what works for you.
