Mesa's KosmicKrisp Vulkan-On-Metal Achieves MoltenVK Feature Parity

I wondered what the value of KosmicKrisp is, when MoltenVK already exists. I discovered these claimed benefits:

• KosmicKrisp is pure open source.
• KosmicKrisp may have higher performance, due to use of the Mesa framework, in contrast to MoltenVK, which is a translation layer, and thus subject to higher costs because of that.
• KosmicKrisp programs may be easier to debug.
• "KosmicKrisp simplifies development and sets the stage for full Vulkan conformance at a pace that can keep up with the Vulkan API as it evolves."
