As I recall, at least one perceived problem with the dramatic difference 
in scale between querying for a host versus query for a user.

I recently noted that Shaken/Stir requires a cert per phone number, 
which seems a rather larger scale of real-world use than certs have 
otherwise gotten, to date.  Not sure how many orders of magnitude 
difference, but likely more than one.
