But I think the parent comment's point is just that if you start with low-level, you can always build on top of it, but the other way around you have to wait for the API vendor to give you the low level access you need.

I hear that you are saying Metal does a better job of being a convenient graphics API than Vulkan. I am just having trouble parsing why this would be an objective problem with Vulkan, rather than you just not being the target audience of this API.
