As are `xxx.example.com` and `yyy.example.com`. I'm hard-pressed to think
of a scenario in which resources from those two origins would be
acceptable, but resources from `example.com` wouldn't.

If there's a need for the granularity, fine. I'm just worried that most
folks making use of wildcards will end up with `img-src *.example.com
example.com`.
