> Native UI toolkits (with “native” defined as system standard) have system hooks and access to functionality that third party toolkits don’t

what makes you think that ? the time when scrollbars were rendered in-kernel is long gone.

I believe the current situation is that first-party toolkits have much more insight into the OS and underlying platform than third-party developers can afford.

And I don't think that this is true. First party toolkits do the very same GL calls in the end than a third party would.
