It's an interesting perspective you have, however I think you are looking at it wrong. Accessibility is not a feature and should never be considered as such. In fact accessibility in webdesign has been a blind spot for many years.

People with a disability are not some marketing target group that you can dismiss, they are a part of the society and should not be subordinated or discriminated. When you build a website that is not accessible, you are in fact doing just that.

Accessibility on the web goes beyond WordPress (see W3.org). These days web accessibility is even required by law in more and more situations.
