Is this potentially a part of why Apple doesn't want to support Vulkan themselves? Because they don't want to implement common Vulkan features in hardware, which leads to less than ideal performance?

(I realize performance is still relatively fast in practice, which is awesome!)

That might be an excuse, but that's hardly a reason. They are simply extreme lock-in proponents and don't want to support cross platform graphics API. That's the real reason.

Which seems like an ineffective move when you have no market share.
