I’m sorry but you’re quite wrong that Mantle was a simple name change to Vulkan.
The mantle API was a foundation but what came out was quite different.
Much of the Mantle team also went on to work on DX12 and Metal as well, so they have as much lineage to Mantle as Vulkan does
The comment you link to also ignores all the context of the timing, including the significant amount of time between when Metal was released and mantle was donated to khronos, and how much khronos was pushing AZDO OpenGL at the time. The post you linked is quite biased and uninformed.
