Also I'm disabled myself, although not in a way that requires any adaptation to use a computer. But I of course notice these things a bit more than average; and I get to hear my elderly father's complaints about software that he can't use because of inaccessible design.
Of course a designer should be qualified and notice these things even more… but all they do is move buttons around and disable copy paste so that even fully abled people have a hard time using our software between versions.
The second group does make things that look nicer, but the first ensures it can be used. You really want both, but then you need to be careful about who wins when they disagree.
