I see a few more places that reference this in codesearch that I don't see in
your CL:

Thanks Alexei for pointing this out. 
The ones that were not in this Cl described below:
- policy_test_cases.json
    will do that at the same time with unittests within this Cl, if     
    this change will seem reasonable to reviewers
- prefs_util.cc
    removed the reference, but didn't add anything instead. Not sure     
    about this
- privacy_page.html
    according to previous conversations I had, a new privacy page        
    was getting designed however the development was stopped and 
    there are no plans. So I disregarded this file.
