While I argue your response is an equity Vs equality issue and your basketball argument kind of conflicts your previous statement, there is the the huge difference of individual cost per game to cater to a/all disability. As you mention automation of these systems aren’t really feasible and although guidelines can be put in place. They are still a significant investment of time and money. You can implement them into an engine but you still need the game to integrate it and although some things might be easy across multiple games (colour blind overlays) some won’t (mechanic driven considerations).
