It's more because of a limit in the system they use. The ZoneAbility system attaches abilities to the zone you're in. This works in the storyline when you get the abilities to try out when you're in the zone they're attached to. After you join a covenant, these abilities become permanent. They can't be handled by the ZoneAbility system because they're no longer bound to the zone.
