If having more options "leads to a confusing mess", I fail to see how having an additional option gets "ahead of this problem."

Having a solution pushed forward by arguably the most influential implementation team is what pushes it forward, not the fact that it's "just another option". Regardless of what Chrome implements (whether it's this, or raw TypeScript, or CofeeScript), the fact that it works directly in V8 is what pushes that solution to the top of the stack.
