Suggested wording: "can include a different dispatcher - but we verify that it's a main thread dispatcher" And maybe explain why this restriction exists (naively I thought all of this stuff was immutable so it'd be safe to access them from any thread)

This part is not for the runtime actually, this is where we collect the emitted renderings from the runtime and update the views that show them.
so we need to get main thread here to update those views.
The wording change is good though!
