This is honestly just out of touch with most modern Web development. Even if its "easy" to develop (which is debatable), if its not a priority with product managers it will simply not happen in today's "more with less" technology industry. Consider also that users who block JavaScript also block most analytics packages (by design)--from a data-driven product management standpoint, users who block JavaScript literally don't exist. Web QA is hard enough across multiple browsers and OSes; adding to that a second version of the site for users whose presence can't even be quantified is not going to be popular.
