Disability legislation doesn’t design solutions: it provides requirements which are inputs into your design process. The solutions are up to you.

I was replying to a post explicitly suggesting that the APIs and UI for accessibility should be standardised. In that context I think trying to refute, er, the suggestion actualy being made, is reasonable.

I’m not suggesting that — I thought you were speaking metaphorically. If a court mandates that Apple allow sideloaded apps or third-party app stores, it will obviously take the same form as accessibility requirements, not specific APIs or UI designs.
