The way I see it, keeping it in the markup makes it more straightforward to debug. If it's server-side, all of our developers need direct access to the asset server as soon as there are content negotiation issues. If it's client-side, we can share a highly-available asset server and each developer has their code sandboxed. In an ideal world, it would be server side. But it would easily mean twice as much work to get there.
