I've seen some folks use assertive instead of polite for the aria-live setting in a flash/toast context. I'm unsure if there is a defacto one to use in this case though. Open to feedback!
I think for most cases "polite" seems like a reasonable choice. In any case, its part of CoreComponents, so if users desire they can easily alter the default.
This nicely notifies screen readers and such of changed content/alerts.
See aria-live for more info.
