That might be a problem with the implementation, but it doesn't seem like a reason to restrict the functionality. For what it's worth, my testing didn't find any perceptible issues with this patch.
Of course, there's no reason to restrict the functionality if you can find a way to make it work correctly. But I don't think XTest provides a way to distinguish injected events.
