OnProcessShader always comes in shader type:[Vertex] only when building apk

hi there
i m putting together some shader stripping machanic with OnProcessShader callback, and i log every piece of info comes back with the api on android build.
the logs indicates that all the callbacks were of ShaderType:[Vertex] only.

i even explicitly put a if check to see if there is any non-vertex shader type came through at all with LogWarning.

and nothing came through at all

Question : is this normal ? OnProcessShader callback only let us handle Vertex shader?? or was there some bug in the internal ShaderType feedback through OnProcessShader API ???

btw:: i am testing this with URP setup on 21.3.6, only with a simple scene containing 1 simple multi variant shader in it, and the build only contains this simple scene as start up, so its just simple plain test ground for OnProcessShader api really, nothing speccial.

Hi!
We combine all stages internally for GL and Vulkan. So what you see is completely normal.
