Here you are talking about raidz? You can add a disk to a mirror
but that won't add any usuable storage.

It was the middle of last year, judging from this post:

I'm happy to confirm that this P6T (ICH10) system works happily in
native or IDE mode.

Swapping controller modes is certainly something I wouldn't have
attempted prior to ZFS boot!

I think that's the autoexpand property.
You could always expand before that, but exactly when it happened
wasn't well defined and changed from one release to another.
In the original release, expansion happened automatically, but that
caused problems in some cases (e.g. a LUN grew the instant you detached
a smaller mirror side, and you couldn't then reattach it). This was
subsequently turned off, but you still got LUNs growing if system
happened to reboot. autoexpand property tidied this all up, but
expanding LUNs has always been there.

That's right.
