I'm still looking for a _single_ example of user agent support for
reactive conneg _at the HTTP level_. srcset, as far as I can see, has
entirely HTML-language-level semantics, and has nothing to do with
HTTP. It also, at first glance anyway, seems to be exactly the kind
of conneg anti-pattern which got such a bad review from the HTTP WG in
the thread on Mike Kelly's suggestions about changing the semantics in
HTML of a/@type and/or adding a/@accept, starting at [1].
