@matt @jscholes @tunmi13 And what happens if the main Window ever gets destroyed or recreated? While I can often hook into app startup, most mod frameworks don't allow detailed hooks into Window Creation. It's possible I'm missing things, and smarter people than me can come up with a way to make this generally viable. But based on my research and skill level, I just don't see a path to avoid screen reader libraries in the majority of cases. Live regions are only useful in the case where you're writing your own app from scratch or modifying an open source app, and you never need to alert the user to things when the foreground window doesn't have the focus. This is a vanishingly small number of cases. As far as I can see, screen reader API's, and robust libraries to call them, are going to be useful for years to come.
