Back in the day, anime magic was king and toy/model designers would always have headaches trying to reconcile proportions in all 3 modes.
Today, there is CG animation and accurate 3D modeling, but Bandai still managed to pull out the V1 VF-25. That aside, I never got a VF-22 (despite the discounts) because of the tiny limbs, in fighter mode (my favorite) it looks great though.
