Yeah, some popular bases, such as TDA, have unnaturally long calves too, but actual humans will have their heels under their butt when they are sitting in seiza or squatting, not far behind it like your or a TDA model would. Internal limb proportions affect both dances and sex motions rather drastically, unlike thiccness, which merely requires clipping control.
Remembering to keep the far limb halves (forearm, lower leg) at approximately 0.9 of the parent half's length is a good and easy method of avoiding unpleasant joint rotations when you use IK chains and a lot of clipping, which usually affects non-IK limb movement.
