Increasing contrast doesn’t hurt anyone (though dark mode users generally prefer slightly lower contrast for lower luminance overall). Increasing type size doesn’t hurt anyone but might make HN users complain about information density. I think there's enough human variation that it can be hard to say anything general like this. Setting aside the semantic debate about what is a disability, or what is accessibility, let me take for granted that "attention disorder" is a thing and anything that anything that distracts a reader could hurt. It is hard to determine flat-out which complaints are valid. I like to watch captioned content. Others find it distracting, or hate having the punchline to a joke come early (usually due to bad captioning!). I am hearing and AFAIK don't have an audio-processing disorder. I don't "need" captions, otherwise it would probably be a clear case of definitely my needs override someone who just doesn't "want" captions. But that's also another semantic debate. I don't think that should be used as an argument for not trying to improve accessibility in the first place. But it certainly is something to continually improve.
