Feature Request Vertex color support in Default HD material

I was just wondering is there a specific reason as to why vertex color is not supported in the default shader(I mean the default HD/default RP material)?
If it's possible then could you please add support for it or maybe provide a lit shaderGraph with all the default features and properties as the default LIT shader as it's a hassle to do it every time I need it and can't use the default shader for that,
Right now I'm using UModeler and to use its vertex color feature I need to import the pro builder shader which just has a texture variable exposed and no control for smoothness which really makes the scene look ugly in dark areas, so it would be really helpful have it as I don't really want to implement every single feature lit material has in shader graph
