Is Dawn stable yet?

I'm using the Dawn backend on a Mac device, but I'm having a lot of problems.

Such as:

2022-09-29 10:49:22.914 DoeverCreator_debug_arm64[3223:25387] Metal API Validation Enabled
GrDawnGpu: ERROR type 1, msg: Tint SPIR-V reader failure:
Parser: error: 'textureSample' must only be called from uniform control flow
note: control flow depends on non-uniform value
note: reading from module-scope private variable 'vTexIndex_S0' may result in a non-uniform value

 - While validating [ShaderModuleDescriptor]
 - While calling [Device].CreateShaderModule([ShaderModuleDescriptor]).
GrDawnGpu: ERROR type 1, msg: [Invalid ShaderModule] is invalid.
 - While validating fragment stage (module: [Invalid ShaderModule], entryPoint: main).
 - While validating fragment state.
 - While calling [Device].CreateRenderPipeline([RenderPipelineDescriptor]).


So is Dawn stable yet?
