I'd agree with this assessment. Moreover, if developers were to stick with the eminently satisfactory CUA (IBM's Common User Access) interface standard and further regularize that then things would be much easier. https://en.wikipedia.org/wiki/IBM_Common_User_Access

If developers want to experiment with various UI configs then let them but keep a CUA in the background that can be called upon by machines and humans alike. (Unfortunately, ergonomics has never been a strong point for developers.)
