Think about the pitch for removing the feature, "So, we're going to make this in the OS, where visually disabled users cannot highlight anything in any application, can't move text between applications, cannot get the window title, cannot get the window tree, cannot have applications automate or know where other applications are, and basically they won't be able to use their computers. But everyting will be super private. Even the human using the computer won't be able to read it." This is what modern linux desktop computer is on waylands thanks to this toxic privacy meme. It literally just doesn't work for me.
Privacy needs the kind you're talking about simply don't exist on desktop computers where the human actually controls everything (as opposed to smartphone model where the user controls very little and applications are hostile and opaque). If you want to break accessibility and functioning of smartphones, fine, go for it. But leave desktop computers alone.
