I am not a graphics programmer, but this procedural geometry reminds me of "tessellation" from ten years ago.

  Tessellation has been in metal since it’s release or close to I believe.

    Tessellation debuted in Metal in 2016, so yeah, relatively shortly after the first release on iOS (2014) and macOS (2015).

  There are definitely similarities if you zoom out far enough. The object shader (task shader in Vulkan) basically maps to the tess control shader / hull shader, and the mesh shader maps to the tess eval / domain shader. One big difference is that tessellation is fixed function and doesn't allow you to control the topology / primitive connectivity within each patch. Another big difference is that the mesh shader runs as a workgroup, which allows things like parallel geometry decompression where all threads of a mesh shader workgroup collaborate in the decompression.
