I believe there is a lack of proof the ergonomic benefits are significant outside of typing tests which are very unrealistic to day to day tasks (unless you have a pure typist job). A bias also exists when many people that switch layouts never touch typed well or properly in QWERTY to begin with, or lose comfort awareness as they forget how to type well in QWERTY. I speak as someone that touch types equally well in QWERTY and Colemak, and think time would be spent better sticking to or learning QWERTY better.
