Well, yes, that's why I said a bitfield of flags like it. I wanted people to understand what I was talking about. Feature flags for iSCSI, haha.
Of course, what often happens in the RFC process is that you get distracted with the needs of today, while totally failing to predict what's going to happen tomorrow. Suddenly now we have hard drives that support shingled recording, so now we'd kinda need a new flag for 2015 era drives, "drags butt during writing." In 2004 when they were grinding out 3720, the storage world was very different. It's been a hell of a decade and we have some great stuff available now. Just thinking back, 4GB was a hell of a lot of RAM then... now I consider 256GB to be a lot of RAM. ;-)
