> I think a solution where scrollbars on android by default do not paint but ones that go through ScrollingCoordinatorChromium are recognized would be best, since that's the behavior we want and it'll naturally allow more and more scrollbars as they are hooked up to the ScrollingCoordinator.

I see, so perhaps

1. We add a flag ScrollbarThemeClient::isCoordinated()
2. ScrollingCoordinator sets the flag when a Scrollbar get registered
3. ScrollbarThemeAndroid looks at the flag and only paint when it sees a coordinate scrollbar
4. Profit!

Sounds reasonable to you?
