Fast charging seems attractive for the small battery in the Pacifica, but it's probably not common or practical enough that they'll ever add it, at least while the battery is so small.
For fun, I did some back of the napkin math, though. The battery in the Pacifica is 16kWh, and ours takes about 14kWh to charge from empty, so I'll use 14kWh. Tesla v2 Superchargers can charge a compatible Tesla at up to 150Kw (for reference, the charger built into the Pacifica maxes out at 6.6kW).
Assuming they were compatible, and you could get optimal charging speeds (you can't - they change depending on battery temperature and state of charge), theoretically you could fill the Pacifica's battery from zero at 150kW in just over five minutes. Even at the 50kW you can get from a CHAdeMO DC fast charger, it would only take about 17 minutes. Again, these are fantasy numbers, and it would be slower in real life, but it's fun to daydream of charging that fast... :-)
