If the CoG is low enough that you are "not at major risk" of braking hard enough to tip forward, you are probably "at minimal risk" of ever needing to put weight on the rear wheels, and at "fuggetaboudit" for need to drive those rear wheels.

The major issue with this (for my team) is pushing matches: for example, during forward pushing you can easily have 100% weight on the back two wheels.
