IMHO that would be wasteful.

I think the devices that were on before the suspend should stay on, because
that's what the user will expect to happen.  For the same reason the devices
that had been switched off explicitly ("by the user") before the suspend
should stay off.  For the others, the rule of thumb may be "off".

I don't think the driver should decide.  It just may have too little
information to make a proper decision.
