Of course fsck only uses it when journaling is enabled.

Try fsck'ing a nearly full TB FS on a production box that has had a dirty
unmount and you will begin to appreciate the adventure a bit more.

This statement doesn't make sense.  Can you post the output you're seeing
along with the mount options in play?

Journaling decisions can be made basically at anytime the FS isn't mounted
or mounted ro using tunefs(1).
