Personally, when it comes to interpretation by the reader, I think that the new generic syntax in the design draft is fairly minor. I don't see how a template based approach will be any clearer; it won't be less clear, but I don't see why it will be clearer. Perhaps you could write down a couple of short examples to show why using templates would be clearer for the reader.
