You're getting downvoted, but honestly I feel like this is the elephant in the room of accessibility efforts.
A lot of them just feel like they're catering to a tiny slice of the user base that would probably be better served in some other way. In some cases, they arguably make things worse for everyone else, like WCAG 1.4.1, mandating that your links have ugly underlines just because some people might have trouble reading them. Fun fact: HackerNews's links are noncompliant, and could get them sued in Canada.
