While I do think the Tesla / 'NACS' plug is a lot nicer/smaller/easier to use than CCS1, what really is the big win here? It's all based on CCS protocol anyway and hence will have the exact same interoperability issues than before.

The big win for interoperability is that NACS as proposed flipped some CCS protocol features from "optional" to "required". The EU mandated some of those optional features. In North America so far it has been a free for all how much of the software protocol manufacturers actually implement of CCS and many truly have done "the bare minimum". That was the bargain that NACS proposed for Supercharger compatibility in the US was that the SAE should have to also start mandating those features. If it gets standardized that way, and it seems like that will happen, a lot of the interoperability issues should start to go away. One of those features was "Plug and Charge".
