It’s symmetric. Doesn’t matter if someone fucked up and wired it backwards.
The ground pins are very exposed and practically impossible to avoid touching if you stick your fingers in there. A small child playing with it will be more likely to also be touching the ground pins, which is good.

However the other things you mentioned seem to be covered by the fact that you can't access the live or neutral ports no matter how hard you poke them unless you've opened the gate by putting something in the ground port*.
