J1772 can't carry enough amps through those pins. So it needs two more huge pins in a separate compartment.

CCS isn't the absolute smallest way to add two more huge pins, but it's pretty close.

Why keep the J1772 connector? Only the data pins are used. I'm sure there's a way to make a connector that's just the CCS part and fudge the data pins into it.

Then supporting the old cars just happens with a dongle.

Don't ask me that, I'm just answering why the decision to keep it caused such a huge connector.
