I would have to say that governments probably do this now. If they are filing access requests to Canada, they're doing it through third parties. Also, given the way the system now works and how hard it actually is to get information.... If you're identified as being media or political, you're amber-lighted, and tiger teams work out on you.
If you're hoping to get your information at any time in this lifetime, you'd better apply as Mickey Mouse, or somebody else—otherwise, you're going into the ringer.
