Is the issue you're seeing that a 400V car is taking up the space that an 800V car could use, so the 800V car has to wait longer for the 400V car to finish? If all chargers are 800V+ that would become a moot point to a degree. We also need to keep in mind that most people will ideally be charging at home. So these public chargers would be for people taking a trip or for people with parking situations that can't accommodate home charging.
