That's a fair point, but the question here is "catastrophic emergency" that takes out all of your spares and you have to limp by on something you found under the couch for a day or two until you can get new drives in. You can imagine whatever contrived situation is most likely in your case. My main concern is that ZFS is just kinda inflexible about some things, (especially disk/pool configurations) and that has the potential to cause real problems in some situations. I've seen a lot of things happen against the odds through the years, so I like to plan ahead as much as possible and try to figure out what my options are for mitigating those risks. Part of that means periodically asking around to see what's changed that I might have missed.
