Rumor is Tesla is backing away from it's universal charging station commitments with other brands.
I hear the connector will switch the NACS standard on perhaps all vehicles, but perhaps not many of the Tesla Superchargers will be compatible even with a connector that fits.
Also, many of the vehicles won't be compatible with Tesla Supercharging. The Tesla Supercharging is not anything like CCS unless its converted. That is why their V1 and V2 Tesla Superchargers (all of them that are less than 250 KW) cannot be made to work for CCS.
CCS is the fast-charging standard for all USA EVs except for Tesla.
The cars also have to run a program to be compatible with V3 & V4 Tesla Supercharging.
If Tesla does not switch to being compatible for CCS cars, it could complicate things even more when the connectors fit but no charge possible. And can get even more complicated on older cars that have the correct fitting adapter that still will not work. And for two reasons. Changes needed at both, the Supercharger as well as in the non-Tesla.
The few Tesla chargers that have Magic Dock solve this problem, but it looks like Tesla totally gave up on that idea. Only three of them in the entire state of CA and they are all at unneeded locations, next to real CCS. Zero Magic Docks in the entire state of Nevada.
But Magic Dock is only for the J-1772 connectors which will slowly be phased out with the new NACS as standard. This is perhaps why Tesla has kinda give up on this idea.
I really don't think there are yet any firm plans for Tesla Supercharging on all non-Tesla vehicles. So it looks like it will be a while before we have a real fast charging standard for all.
