I'm not aware of special handling, other than offering adaptive media
(e.g. matching image resolutions for varying screen resolutions)
I see the "strip" vocabulary in the context of minified js
and css files. And as the server itself is often not aware of the
bandwidth to the client (as it just sends out the reply, which might
be cached upstream in a forward or reverse proxy, there's not a lot of
stuff to do on that end.
