This suggests that the API is extremely silly; although one could
presumably claim that "an estimate" allows one to return anything, I
don't see how returning "20" if the server is feeding you 1 byte/second
can be helpful to anyone. If no one plans to implement this as a loose
proxy for "type of connection" the spec shouldn't pretend to do more
Can you point me to the discussion of usecases that led to this design?
