  I don't know. A non-directional/non-polarized plug would just omit the features that engage the key-ways on the side enabling you to plug it in whichever way you want. If you want to make it directional/polarized just engage the key-ways so the user can only plug it in one way. In North America we have these[1] for things that don't have a metal case and on cheaper devices both blades are often the same size allowing you to plug it into an outlet whichever way you want.

    What parent is getting at is that Socket Type F "Schuko", one of the most popular socket types, is completely symmetrical and inherently non-polarized. Since any plug compatible with Schuko is non-directional calling non-directional plugs rare is factually wrong (if we talk globally). It also proves your point that the difference between life and neutral largely doesn't matter, since in about half the world wall sockets don't care about the difference.
