Or you as a developer could just avoid alienating disabled people, who likely represent a large proportion of your target audience - whether you realise it or not?
Heading down this path, while valiant, must be done carefully. Otherwise, Google/Apple/Microsoft/Amazon etc will be the only people with the budget to allow for full compliance to every possible disability that may effect the use of their product. I'm not convinced you understand just how much time and energy it takes out of actually delivering a product on a limited budget (in Nord's case free).
Your use of "alienate" has venom behind it that makes me think you're implying they do this deliberately to spite people with disabilities. Occam's razor.
You really need to have actual humans with disabilities look at your website to find out if it works for them.
