Related to this, what about passive powers/effects that have no other tangible affect on the world? Coraline here has a passive magical illusion that allows her to appear human, as it's canonically a sanity-breaking event for her to be seen without it, for both her and the witness; and also a minor magical effect that marks her as a member of a political court, that manifests as an interesting but harmless scent. Would these both be able to be kept when the rest of her powers get clamped down?
