While this might make sense initially, holonomic actually starts looking very bad after viewing the COFs for the wheels.

10.2.4.1 Wheels
The wheels supplied in the 2009 KOP are very different from previous years’ kit wheels. The
tread material is Celcon M90, and has the following coefficients of friction on white, rippled
fiberglass plastic sheet
Inline, static: 0.06
Inline, dynamic: 0.05
Transverse, static: 0.14
Transverse, dynamic: 0.10

Yes, the transverse COF is very low, but the inline COF is less than half of it! This means a holonomic drive robot (with the COG in the middle) theoretically wouldn't move at all! In practice, it might, but not much.
