There are many sites where www.foo.bar points to different web than foo.bar. Random example that comes to my mind is http://opensuse.com/ and http://www.opensuse.com/. This sucks. I'm probably not the only lazy men in the world and typing www everytime is pointless.
So I much appreciate www. is deprecated website, which tries to persuade people about pointless keeping of www in many cases. So if you can, please classify your site as Class B, which is the best solution right now.
