ZFS ZFS on FreeBSD 13 and installer.

I have noticed when choosing 4k sectors, it does not use ashift 12 when creating the boot pool, but perhaps even more worrying the zdb command to view ashift doesnt seem to work anymore. Whilst using zpool get ashift reports a value of 0.

So how do I see the live ashift value on openzfs?
 
Had to manually specify the cache file, and that does report ashift 12 so I guess the sysctl was set by the installer, but I do hope in the new openzfs the ashift variable can be changed to report the value rather than the input (0 been autodetect).
