Fun though the idea is, assistive technologies such as TTS will also have problems with it.

Accessibility should only ever be an addition, never a limit.

Why should that be true?

Because proposing to limit something needs better justification than a fundamentally limited group can't use it.

It's an out of place performative moralism.

We will all become, or temporarily be, fundamentally limited at times in our life.

It's trivial to build something that accommodates an ideal user, the challenge in software engineering is creating a solution that suits many kinds of people, at different points in their life. Refusing to engage with that challenge is a kind of proud mediocrity.

Engineering is fundamentally about building within limitations.
