Yes but you are trading off a lot of people with a one kind of disadvantage, dyslexia, for the benefit of very very few people with a motor skills disability that affects their ability to draw or manipulate an input device which is a different disadvantage. What's the acceptable ratio? One handless person enabled for every 100,000 dyslexics sidelined? Is that fair? How do you work out an acceptable tradeoff?

It is not a given that everyone can or should be enabled to do everything possible at any cost; people in wheelchairs can't be firefighters and we don't make all old subway lines fully accessible because it is incredibly expensive.

Disadvantaging a huge number of people for the benefit of very few has a societal cost.
