Looks like an interesting workflow, but I think I still prefer using a compile-to-js language like CoffeeScript over the use of shims. I know it's a silly thought, but to me, shims sort of violate the separation of responsibilities between the user and the developer. If I, as the developer, want to write more concise, scalable, and convenient code, it should be my responsibility to spend my development resources to convert that code to something the user's browser can understand.
