You really don't understand how much money Apple's sunk on this and how little comparatively it takes to wind down operations in a way that makes partners and suppliers happy. Keeping a couple small teams going, even with entirely new versions shipping, to keep your supply chain whole and your partners coming back for future products is cheap and easy and very likely what Apple's doing now that most of the top talent was moved to spectacles and Siri. Letting your OS and partner software teams clear their pipelines is absolutely common at Apple and elsewhere. Denying that is silly.
