My criticism is that the design limits the places where they are valid. I'm not trying to use a hammer where a screwdriver is required, I'm saying that if the hammer was designed differently, we'd be able to use it in more situations appropriately.
It's as if someone created a gun that fired backwards and I said "hey, it might be better if the gun fired forwards. we'd be able to use it in more situations." and people responded with "you shouldn't use a gun that fires backwards if you want to fire forwards." I totally agree, but it's missing the point.
