Re: Service Provider Status (ISSUE-137)

I don't follow why you think information about a backend service provider would be unusable.  The benefits to users, user agents, researchers, and policymakers remain.

If we give backend service providers a free pass on signaling, I fear we establish a perverse incentive to diminish transparency even further.
