These assumptions and implications seem to be going the wrong way. When they first took it off of the website, it turned out the 75kwh models were all getting the lower power charger, and the 100kwh models were all getting the high power charger. Considering that they are doing the same thing with the Model 3, where the lower battery capacity gets the 32A charger and the bigger battery gets the 40A charger, this would seem like the more likely situation, rather than this assumption that all Model S are getting the higher power charger.
