I'm not 100% sure you're right, but I'm one who did not touch type QWERTY properly. It could be because of the reasons you stated, or because I learned to type on a keyboard myself, not even knowing I should be using touch type. And I found that learning touch typing together with Dvora was great, like you say. It felt very natural with Dvorak, but I don't think the touch typing I learned made me touch type Qwerty properly. I think there's something to be said about starting with a clean slate on the keyboard layout so you don't have to unlearn old bad habits in the process. For me learning Dvorak had the double benefit of making me type 100% correctly with the new layout. I'm really not sure I would have been motivated to do that if I decided to stick with Qwerty. Getting two comfort improvements with one training period makes it more worthwhile
