>WSL
Ah, that explains part of why I couldn't find it. I was searching mainly for WGSL. Something Like 'WEBGPU minutes "Unity" "HLSL" "WGSL"'. There was also WHLSL also from Apple at one point but was later droppped in favor of WSL.[0][1]

The "we designed the language to be source-compatible with HLSL, but we realized this compatibility was not what the community was asking for" comment is funny because Unity's "We care about HLSL" comment seems to be directly against this.
In any case, this is really a disappointing move from Apple. Just another example of them ignoring developers – even large developers like Adobe and Unity – over completely petty disputes and severe NIH.
The craziest line in the post is probably "[WSL] would make it an easier compile target for whichever language their development shop uses." It's like they knew people wanted SPIR-V but they wouldn't do it due to some petty legal drama that Apple invented and then chose literally the worst of all worlds by making yet another compile target instead of at least choosing the next best thing which would be something that is compatible with HLSL.
