This is my point of view as someone who learned WebGPU as a precursor to learning Vulkan, and who is definitely not a graphics programming expert:

My personal experience with WebGPU wasn't the best. One of my dislikes was pipelines, which is something that other people also discuss in this comment thread. Pipeline state objects are awkward to use without an extension like dynamic rendering. You get a combinatorial explosion of pipelines and usually end up storing them in a hash map.

In my opinion, pipelines state objects are a leaky abstraction that exposes the way that GPUs work: namely that some state changes may require some GPUs to recompile the shader, so all of the state should be bundled together. In my opinion, an API for the web should be concerned with abstractions from the point of view of the programmer designing the application: which state logically acts as a single unit, and which state may change frequently?

It seems that many modern APIs have gone with the pipeline abstraction; for example, SDL_GPU also has pipelines. I'm still not sure what the "best practices" are supposed to be for modern graphics programming regarding how to structure your program around pipelines.

I also wish that WebGPU had push constants, so that I do not have to use a bind group for certain data such as transformation matrices.

Because WebGPU is design-by-committee and must support the lowest common denominator hardware, I'm worried whether it will evolve too slowly to reflect whatever the best practices are in "modern" Vulkan. I hope that WebGPU could be a cross-platform API similar to Vulkan, but less verbose. However, it seems to me that by using WebGPU instead of Vulkan, you currently lose out on a lot of features. Since I'm still a beginner, I could have misconceptions that I hope other people will correct.
