Although your advise is a sensible one....
It does not work if the ZFS system is full of data, and it's
hard/impossible to rebuild.
I have experience the other way around. My ZFS raidz2 is pretty old,
probably even from the 7.x times... And I've upgraded it regulary to new
I even upgraded to v28, to be able to remove log's that we on USB sticks
and all. No problem at all. And I do have removed logs quite a few times
to look at different configs with my SSDs.
Again: if you have te possibility to rebuild, why not.
