I think there are multiple versions of this (I also have one[1]) but the concern is that if one creates a pool with ashift=9, and now ashift=12, the pool gets unimportable. So there need a way to disable this behavior. Another thing (not really related to the automatic detection) is that we need a way to manually override this setting from command line when creating the pool, this is under active discussion at Illumos mailing list right now.
