It didn't require it until robots started getting extremely heavy.

When the unlimited raw materials rules started taking hold, robots started getting heavier and heavier in FTC. My senior season our robot weighed 68 pounds. We still built our base frame out of Tetrix back then. Now I know for a fact 3864 has gone away from using anything Tetrix in the drive base with the exception of the wheels. Tetrix parts just were not made to handle the weight that the FTC teams put on them now a days.
