Yeah, that's cool, I'm not picking a side - sides suck, they're divisive. It's my belief there are benefits to both approaches (server-side and client side). I'm just pointing out a problem with the viewpoint that the server might be relied upon for a particular feature when the logic that lead to <picture> itself negates the argument of using the server for that feature within <picture>.

>> Again, the reason <picture> was decided as preferable was the assumption that server-side negotiation was "too hard" and there are currently problems with the scaling factor. If that's the case, then we should also be chasing client side solutions for file-type negotiation, not just URI resource negotiation.

Won't that cost problem go away once it's a common option? I do not want us to throw out a good, powerful, solution just because there are current problems for a small (yes, small) use case (i.e., site's that run at huge scale). The majority of sites on the web aren't Adobe.com (http://Adobe.com).
