"The more ARIA attributes that were present, the more detected accessibility errors could be expected"

This sounds about right for the current state of attention paid to assistive technology. Which is to say, it's an afterthought at best. Buying or installing some half-baked framework which attempts to use it correctly without even determining if it's correct or not and calling it good seems about as far as anyone will take it. One could make an analogy with left-pad: easy to use, but turns out it does the wrong thing for several cases.
