I think WebGPU is a like a minimum common API. Zed editor for Mac has targeted Metal directly.

Also, people have different opinions on what "common" should mean. OpenGL vs Vulkan. Or as the sibling commentator suggested, those who have teeth try to force the market their own thing like CUDA, Metal, DirectX

Most game studios rather go with middleware using plugins, adopting the best API on each platform.

Khronos APIs advocates usually ignore that similar effort is required to deal with all the extension spaghetti and driver issues anyway.

Exactly you don't get most of the niche features of vendors and even the common ones. First to come in to mind is Ray Tracing (aka RTX) for example.
