I know this case was Self Review and I agree with it being self review. It is after all a debugging tool.
As a ZFS developer I've been using this tool already and it has been a huge help to me debugging problems with ZFS Crypto and send|recv. I see very little use for it by normal admins and users because unless you know how the stream is formatted and know how ZFS really works (especially how send|recv work) its output won't be that understandable. Traditionally tools like this wouldn't have been packaged at all but would have been available in bfu archives only. The plan is that bfu will go way sometime after the transition of ON building SVR4 to IPS packages so internal tools now need to be packaged up. With my ARC hat on +1 to this case - even though it doesn't strictly need it. -- Darren J Moffat
