You'll notice that no one in this thread has claimed that EPUB2 "is based on" CSS 2.1. Rather that; where a single specification must be chosen for the inexact validation of CSS in an EPUB2, CSS 2.1 was the lesser of two evils.
Regardless: the user will have a preference setting (in the next version) allowing them to choose which CSS version they wish to validate against.
