> If something actually better came up, you'd eventually see it mandated.
While I generally am quite content with that particular mandate and it does more good than bad, I would have to disagree on this. Something better doesn't come from nowhere - hell, USB itself has gone through a long and arduous path until it came to the (messy) standard it is today. This is essentially banning any other standard to grow and be improved upon with feedback and iteration.
I don't believe other paths would yield better results.
It took Apple a looong time to adapt USB-C, which was already running circles around Lightning five years after the introduction of the latter. Ironically Apple participated in the development of the standard. They just couldn't be arsed to implement it.
Multinationals don't do anything unless they absolutely have to. Apple notably all but threatened to move out of the EU due to USB-C regulations. They were actively preventing their users from having a better standard because it hurt their bottom line in the field of accessories.
