These aren't necessarily in conflict.  The base url and the origin are
distinct concepts.  The origin of a resource hasn't been important in
CSS so far.  I expect that as more resources with origin-important
behavior become usable in CSS, we'll remain consistent with what the
Fonts spec is saying.

Putting any kind of support resource (by which I mean something that's needed for my site's operation but does not by itself result in visible output) so as to make my site work, is not permission for you to filch bandwidth from me by using it to support your site as well.

To put a finer point on it: fonts are the first large resource that
doesn't have too much legacy hot-linking behavior already for us to
clamp down on it.  Many browser implementors (and I as well) would
*love* if we could go back in time and make images SOR (obviously we
would need to take CORS back with us on the time machine as well).  We
*just barely* missed the boat on <video> and <audio>, which is
terribly sad.  (Though, I'd suggest that we apply SOR to video or
audio resources linked through CSS, however that is done.)
