ALS is a configuration. Blindness is a configuration. Conventional UIs are built for a different configuration. Accesible UI usually overloads the conventional. If you start from scatch, sometimes you find something new. If you're lucky, the new thing scales to other configurations.

For example, I wrote a NLP parser for a calendar app, at Tempo.AI. It was much more efficient than the visual interface. And thus, it was accessible. But, it didn't use the accessible idiom. Instead, it was universally more efficient, whether you are blind or not.

A good example is a wheelchair accessible doorway. One method is to have a button at wheelchair height. The other method is to have the door open with an electronic eye. The first is Accessible. The second is Universal. Doesn't matter if you are in a wheelchair or not. It's a throughput multiplier.
