No, I mean, for example, ISCSI_TCP will just "depends" on SCSI_ISCSI_ATTRS but 
SCSI_ISCSI_ATTRS is Lazy_Enable. So a user can always choose ISCSI_TCP if he 
wants to. At the end if there are no users for SCSI_ISCSI_ATTRS it is dropped.

Lazy_Enable is for these modules that say: "I have no purpose of my own
but only serve other needs"

Theoretically it looks like a simpler problem. (Pull vs Push)
