What's the reasoning for making this a note? I don't think it needs to be, it works just as well as a paragraph.

No particular reason; I think you are right. I have updated them to normal paras in the next commit.

| > You can omit the `entryPoint` property if your shader code contains a single compute shader entry point function — the browser will use this as the default entry point. If `entryPoint` is omitted and the browser cannot determine a default entry point, a {{domxref("GPUValidationError")}} is generated and the resulting {{domxref("GPUComputePipeline")}} will be invalid. |

Does "a single compute shader entry point function" mean "a single function with the @compute attribute set"? Is it worth saying? It's a little odd (to me) that we use this precise formulation in the previous para, then the more general one here.

Yup, this is correct, good point. I've updated all three similar instances to the suggested form in my next commit.

Description
In Chrome 121, you can omit the
entryPointproperty values of the compute, fragment, and vertex shader object definitions contained in the configuration objects ofcreateComputePipeline()/createComputePipelineAsync()andcreateRenderPipeline()/createRenderPipelineAsync(), provided your shader code contains a single function that the browser can determine as the default entry point.This PR adds information and validation entries about default entry points to the above pages.
See https://developer.chrome.com/blog/new-in-webgpu-121#default_entry_points_to_shader_modules for evidence of the addition.
