Andras made a bunch of improvements to the wiki page recently: https://ext4.wiki.kernel.org/index.php?title=Ext4_Disk_Layout&diff=9155&oldid=9147 What I was trying to type (and failed, because I was composing too quickly), that Andreas made recent improvements to the wiki page, and thanks for that.
