Vulkan is Mantle. Vulkan was developed out of the original Mantle API that AMD brought to Khronos. What do you mean "AMD should just go all in on Vulkan"? They've been "all in" on Vulkan from the beginning because they were one of the lead authors of the API.

Vulkan is a derivative of mantle sure, but it is quite different than what Mantle was.

There was a period in between where AMD basically EOL’d mantle and Vulkan wasn’t even in the works yet.

I would say vulkan derives from mantle, mantle development stopped some time ago.
