isn't the reason for that that the API as it is now does not say 
anything about how the location exposed through the API is obtained? the 
API only talks about how applications (consumers of the API) may be of 
concern privacy-wise, but it is silent about the fact that in many 
cases, the implementation of the API also has some privacy implications, 
in particular if the location is not determined locally on the device 
(via GPS) but through a location service provider. this becomes 
particularly relevant if that provider stores the location profile of a 
user, and also is a major mobile advertising player. the recent press 
coverage of the updated iPhone/iOS 4 privacy policy reflected the fact 
that the "back-end" of the API also can be very relevant from the 
location privacy point of view.
