The only difference is the DataTypes, so you can view files with MultiView.

AFAIK, there's nothing in the kickstart that has anything to do with datatypes. There are all kinds of other issues when using a 2.x kickstart though. And regarding 3.9, there's no problem setting up 3.9 to be equally stripped down as 3.1 or 2.x, it just takes a little bit of effort.
