Did a bit of searching & it appears it was only changed on 15/7/20, but no, I certainly don't remember any discussion? https://wiki.openstreetmap.org/w/index.php?title=Template:Admin_level_10&diff=prev&oldid=2012028 Makes reference to "Australian Tagging Review (2012 / 2016)", but that doesn't help me much either?
