In my opinion, mandating autosense in an environment such as iSCSI (...or 
FCP ... or SBP-2) provides the cleanest solution.

The greater "you" (designers of iSCSI) are free to make of it whatever 
seems advisable. There is nothing forbidden in a SAM-compliant transport, 
whether FCP, iSCSI or SBP-2, from requiring autosense capabilities in the 
endpoints.

As you can tell, I think it would be a good design choice to limit iSCSI to 
these devices. I also think you would not find it limiting, but that's a 
different thread.
