I'm not sure - we usually prefer to evolve as real use cases show up
instead of aiming for the final design in the first place (which, as
practice shows, most likely anyway have to change when the real use
case show up).

This usually proves itself as the minimum effort for nailing the
existing requirements (less code to develop, debug and maintain).

We also want to support powering off the cards even if their driver
isn't at all loaded (as I wrote previously).

Oh I thought you volunteered ! ;)

Thanks,
