EV chargers have a standard that everyone other than Tesla uses. EU is basically forcing usb-c to become the standard for phones and laptops (it already effectively was except for Apple phones). The plugs in your house have a standard. The batteries in your remote have a standard. The various mechanisms by which we are communicating over the Internet have many standards. Standards are regularly implemented and entirely possible.
Not saying anything about this implementation but standards are incredibly common and more the rule than the exception. They don't even need to be followed 100% to be effective.
