You're right, the core isn't really any more suitable place to set the
preferred profile than module-card-restore. The problem with module-
card-restore is that it should only be about making the card state
persistent, so this kind of policy goes beyond its mandate, and the
problem with the core is that the core shouldn't really decide this
kind of policy. Creating another policy module just for this is
probably overkill. If you want, you can move the code back to module-
card-restore. I don't really have a preference any more.
