At the moment we fire the event before all the components are created, destroyed. We need to change that to only fire when everything is completed. The reason being is that sometimes (most of the time) when we get an event and check Services.appinfo.accessibilityEnabled it is not in sync (e.g. we might not or still have a reference to an a11y service that is being created or destroyed).

I think I am, yes. Having Services.appinfo.accessibilityEnabled not in sync really hurts. There is then no reliable way to know when accessibility is truly shut down.
