Robots with arms extending on the sides more that 16"

I have seen many robots reveal with robots using arms to accommodate other robots that are more than 16" outside the frame perimeter to the sides. Did some rule change that we are not aware of? is it legal? what does teams are doing if accepted will not be fair.

Robots can extend more than 16" outside their perimeter during the endgame while inside the platform zone. See G05 and R04.

the 16" rule does not apply during endgame inside the platform zone, per G05
