Well, it *was* by design, but now I'm changing the design. It's a good time for it, since 4.0 is about to come out. I think the security teams can move on and we'll consider this "changed" rather than "fixed" for 4.0, where we do some security tightening.
Since you do seem to be willing to ponder the system of access rights and its security implications: I haven't checked the 4.x prereleases yet, does being authorized to see a host's information still necessarily provide access to *all* services on it? In the "customers accessing provider's Nagios" scenario, I suppose that the customer might be interested in seeing "application is running" but not, say, "the snmpd that ties this machine to the provider's NMS is acting up" ...
