More internal details about implementation in http://scst.sourceforge.net/scst_pg.html. Features which are implemented in http://scst.sourceforge.net/comparison.html. Directly on the subject you can find some considerations in http://lkml.org/lkml/2010/10/1/140 (second half of the message). My opinion is that in ideal the SCSI initiator subsystem should be drivers/scsi/initiator and the target subsystem - drivers/scsi/target with shared code in drivers/scsi/. But in reality such big reorganization is unlikely possible, so it's better to leave SCSI initiator subsystem in drivers/scsi and the target subsystem - in the separate directory in drivers/ (drivers/scst for SCST).
