Probably because it's a) trivial and b) not always feasible (you don't
always have enough disk space and/or network bandwidth or can't afford
time to make a verbatim image of an entire drive of a system to be
repaired).

If by making an image you imply not dd, but "zfs send", then you have
to import the pool anyway.
