It isn't. It doesn't for example do three phase AC. 400 kW CCS type 2 combo chargers are being deployed right now. Where are the 400 kW chargers on the Tesla plug?
North America now has a painful switchover from CCS type 1 and Tesla's proprietary charging to CCS type 3. Teslas 2019 and earlier will need a CCS retrofit to use all chargers.
North America could have and should have standardized earlier.
