What do you mean by standard? These connectors come in various sizes and pin configurations, there is no standard to speak of. There's only a small number of them, easily convertible with a passive adapter; but some of the ones with an ID chip do need to go away, preferably replaced by resistor-sensing for higher power outputs. I don't think that I've ever seen laptops of different manufacturers to be able to use the same charger. The actual manufacturers are Compal, Inventec, Pegatron, Wistron, etc. and they can definitely use the same charger. The point I'm making is there was already a convergence towards a simple de-facto standard for laptops, one that has been in existence for over 2 decades. Yet the EU decided to force them to change to the most complex standard, with far more fragile connectors.
