[Idea] A potential path forward for Metal API implementation via Vulkan translation

[namutachi-webtachi]

Hi Darling team,

I was just thinking, recreating the entire Metal API from scratch seems incredibly difficult. I was wondering if a different approach has been considered?

There is a project called MoltenVK that translates Vulkan to Metal. What if Darling did the reverse? A 'MetalVK' that translates Metal calls to Vulkan.

This way, Darling could leverage the mature Vulkan drivers on Linux (Mesa) instead of building a whole new graphics stack. Also, since Apple maintains backward compatibility for Metal for a few years, the translation layer wouldn't have to chase every new macOS release.

Just a random thought from a fan. Thanks for all your hard work!"
