If you need FCoE target only as a development/testing ground to see how it works or to test FCoE initiators, I also agree with you. But if you are going to use it for a serious production usage, for instance, for producing FCoE-capable storage devices, that would not be a wise step, because you would miss many very important for production usage abilities and features. See for more details http://lkml.org/lkml/2008/12/10/245 and http://scst.sourceforge.net/comparison.html. Since the first SCST patches review iteration in December 2008 popularity of STGT, despite of being "mainline", has not grown noticeably, while popularity of SCST has significantly grown. Particularly, Emulex and Marvell added SCST target drivers for their hardware and many storage companies are now either selling SCST-based storage devices (see http://scst.sourceforge.net/users.html), or preparing to sell them (so not yet listed on the users page).
