This is a good question. I would assume that if someone has an external GPU they want to use it. And it is likely that their display is running through it or, even if it's a laptop, they are using it as the primary display. So we should probably use any external GPU before even checking for the low-power/high-power flag. But this doesn't need to be fixed now.
