I feel the opposite. The more computer interfacing takes place in software, the better for disabled users. If you have a device that expects a keyboard scancode to respond, then you need to build a physical keyboard to talk to it. Building a physical keyboard that doesn't suck is expensive, and so disabled people pay crazy prices for gear tailored to them.
Tailoring software that can use very general-purpose input equipment is much cheaper. Training a neural net to recognize one-handed gestures, for instance, could be done by one developer then deployed worldwide. Making a decent one-hand keyboard is way less easy and way harder to scale.
