Destination chargers can be even more convenient than Superchargers/DCFC sometimes. Say driving to your destination would use 85% of your EV range. If there is destination charging, you wouldn't even need to bother to stop along the way at a fast charging station, and could simply park and plug in at your destination, with a 100% charge awaiting you the next morning. Literally 0 time lost due to charging, while if there was no destination charging, even a stop at a V3 Supercharger would result in increased travel time.
