They really only codify what has always been. A Citizen has granted rights, and can therefore be ungranted. They then usually give you the reasons those rights can be un-granted, but are rarely specific.

Read section 3 again, it basically says "they gave you the right until they chose to take it away." Hence, I would argue, nothing has changed, except they clarified (codified) what it means to be a Citizen.

Hint hint: If you want all of your natural rights, then change your standing.
