The requirements are generally things that were designed away on purpose from Wayland. Even if KDE plasma had a workaround solution, they would need to communicate with all other distros to make sure all distros have similar solutions so accessibility feature devs don't have to make a version of their application for every distro, and KDE Devs themselves have said that they "don't want to allow users to shoot themselves in the foot by letting the application bypass security features" as if application A knowing the coordinates of a window in application B has any security implication whatsoever.
Wayland is fundamentally designed without accessibility in mind at all, and will virtually never work with it. The current status is still after 17 years "tough shit" and that infuriates me.
Pretty sure they collect it regardless of you disagreeing or not. Block all cookies by default always unless you are on a site where you need to log in.
