Consider that, for caching purposes, you *really* want all the icons to
have a single, fixed URL;  making the URL relative to the content object
would mean that the icon almost never got cached.

Live with it a while longer;  having an easy way to mention the
*site* URL is a blessing (and the tool can do other tricks, like computing
a physical path relative to the CMFSite).

The tool won't go away, so feel free to tilt at windmills if you like. :)
