The author mentions PathFinder, the GPU font renderer from Servo a lot, so there do seem to be existing systems that do things in that way.
I'm not 100% sure though about Apple and other's approach though - definitely when compositing desktop environments were new, the way it was done was to software render UI elements into textures, and then use the GPU to composite it all together. I assume more is being done on the GPU now but it may not actually be all that performance critical for regular UIs (he talks about things like CAD which are more performance sensitive).
