I would not word it that way, but I think we mean the same thing.  Yes,
I do not want to add more hooks for a complete oddball that has no
actual use case.  dm-rq does a good enough job for SCSI and has all
the infrastucture for it.  We should not more cruft to exteded it to
use cases for which there is no consesus and which are much better
covered by alredy existing code in the kernel.
