It has a very good reason & purpose to be mounted where it is, and is part of IEC 60947. Politicians had nothing to do with it ; electrical engineers did....and it's just one of those things that it wasn't implemented in AU until years after the rest of the world adopted it (2011 or so), so blame the politicians for that - this was in response to death/injuries caused by solar panel installations, when the power generation point couldn't be isolated from the field equipment (chargers/inverters).
Not on topic, so I'll leave this here =)
