Do wakelock enabled drivers require a wakelock aware user space to function properly?  If the driver is added you want to make sure the benefit is there and testable for all userspaces.

Early Android service managers did take/release userspace locks to ensure the handoff worked.

Getting all these drivers is positive.  Getting to some constraint mechanism is positive.  It does need to exist end to end to make a difference at the battery.
