I respectfully disagree. First, none of those changes need to be addressed in the GUI or in manuals to simply update the build to 2.3.0 or 2.3.1. There is no reason functionality can’t be added to the GUI, and documented, in later releases...
It takes zero plumbing to update ZFS now. The relevant functionality can be utilized from the CLI (which is where you should be managing ZFS). Future upgrades of plumbing in the GUI shouldn’t delay introduction of the functionality.
