One thing I have noticed is that Apple puts a lot more things in Accessibility, but they all are accessibility features when you think about them. (I especially noticed this with my Airpods Pro.) So instead of being the settings that people with major disabilities use, it's the settings that a lot of people use to make their computer more accessible to them, and by being in there they're more likely to find other settings that make their computer more accessible to them.

can confirm it exists on my mbp running 14.2.1
