We have a number of policies that control content settings. Can the Bluetooth
policy not be implemented the way those other policies are?

As discussed over IM, most of the policies are either chrome-only or go through
the PermissionManager tunnel through the Content API, which Mounir suggested I
not use for this. I'm imitating DefaultKeygenSetting for this one.
