Well in the GL/Vulkan world there's finally functionality now in recent years for printf output from shaders, which finally fixes the issue. I'd assume DirectX probably also has something similar but I don't work with it so I don't know.
Hm .. I just have limited experience with WebGPU so far, but since that is still highly unstable and I really would like a printf functionality and all of the performance possible, I guess I should rather invest all my learning efforts towards Vulkan. Thanks for the hint.
