Okay, great.  

My observation is that the explicit lack of commitment to the stream
format in the zfs(1m) man page is actively scaring people away from
using zfs send.  

I wouldn't insist on it but given the stated goal above, this might be a
good time to formally commit (both as part of this case and in the man
page) to being able to restore old streams with new software.  

(I can understand not wanting to commit to always being able to send in
older stream formats).
