This is a very good start! What would close the loop is an endpoint to serve legally binding notices. Consider someone with a legally recognized special need necessary for some bodily function. For example, someone in a wheelchair wants to use a bathroom. Or two people who can't speak want to get a condom by communicating it non-verbally, by pointing at it or writing their request down on a piece of paper, but whose requests are ignored whereas speaking customers have their needs met. In code you can just try: try usebathroom() catch cant or try buycondomnonverbally() catch cant The exact function call that makes it fail becomes obvious. With an endpoint, you could apply the legal API to it and demand that the proprietor provide legally mandated accommodations until the failing function succeeds for the special case. It's hard to deny you exist if there is a parking lot full of employees and you can serve them a notice by GPS lookup. If someone made that service it would be an "oh shit, they actually mean it" moment for every unaccountable black box Establishment that skirts its accessibility obligations. It would instantly improve the world for everyone.
