First, I applaud David Ball for doing this and sharing his results!
Second, one of the first web application projects that I was a part of I was assigned as the "accessibility expert". At some point during that project I was told that the reason it is termed "accessibility" is because it makes the resource (e.g., website, print page, whatever the resource) more accessible for everyone, not just for people with physical limitations. The development version of that application lived on an unmanaged, but live server for more than a decade before it disappeared; up until its disappearance the application was still functioning, and could even be used on a mobile phone. Most of the recommendations I made, all those years ago, went uncontested by my teammates, but every now and then I had to fight for some aspect and I would make the "accessibility benefits everyone" speech. The last teammember to visit our application before it disappeared admitted that it wouldn't have been able to run on the latest technology if I hadn't been so adamant about accessibility all those years ago.
