I think it's sensitive because one could figure out how many hosts a SP has globally... which a SP might not necessarily want to reveal.

I've proposed a blueprint and spec for a /hosts admin API resource that would return information on physical hosts. However, I don't believe that there's any way for us to actually identify a specific server (I'm actually hoping I'm mistaken about this, because that would make my life easier).
