The completely separate ports for AC and DC charging in CHAdeMO vehicles is incredibly clunky design, though.If Tesla was doing this as "a deliberate choice to enable a more ergonomic plug form factor" I would submit there was a already an existing system that provides that function without the failure mode complexity of AC/DC pin sharing using CHAdeMO for fast charging etc, ie keep AC/DC totally separate in individual ports that are "ergonomic" to use individually.
