Well not yet but starting next year, now GM should follow

Tesla already has CCS magic dock chargers in CA and NY for testing. Many other brands, including some Bolts have charged on Superchargers. This is more of a software integration between Tesla and Ford. GM still has catchup todo on plug and charge capability to get the payment system working.
I see this as perhaps the best thing to happen for the US CCS community, including all non-Tesla EV OEMs and the various CCS fast charging system operators. The CCS standard has some major advantages over NACS, including better V2X, native 800 VDC capability, better vehicle pack/grid isolation etc. They will now have to face the reality they have a very short time window to resolve their equally-major charging-experience issues, including hardware/software/payment/locations/amenities,etc, while simultaneously rapidly expanding their networks, or they will get washed away by the SC network. The charging system war has officially started.

Do not forget the inherent safety aspect built in to CCS. There is no way to put DC voltage input to the onboard charger, and there is no way to put AC voltage onto the battery. Tesla has to address this inside the car with additional hardware isolation methods and safety software.

Exactly. The dedicated J-1772 AC pins and conductors feeding the OBCM and its inductively-isolating transformer provides a fail-safe AC/DC electrical separation both ways. Additionally, CCS sets safe max conductor + pin temp @ 90 deg C (IIRC, this is also the std for the national electric code) but Tesla unilaterally set NACS std safe temp at 105 deg C, which gives them 15% more amp capacity. Will Ford use one safe temp limit for the CCS and a higher one for the NACS?

Ford does not charge very fast, I do not think temp limits will come into play. Top speed on my Mach E has been 160kw, and I think Lightning is 170 kw, but for a longer period.

Tesla has limited the charge rate for the Magic Dock to something lower than 250kw, but I cannot remember exactly what it was set to.

Right now Tesla has a 300-350 Amp limit on the Dock.
