The problem with having anything in "production" on the web is that you can neither update it or change it because people will rely on it.
The idea behind web standards is that there should be at least two independent implementations, tested behind a flag, with iterations on design, before it becomes a full standard.
Chrome's approach for the past several years has been: spit out a half-completed spec, "ask" other browser for input.... and ship it in prod a month later.
