That's about it, if you are referring to the parallelism of the hinge axes in plan view (or side view). You also get some weirdness in your bump steer curve for free. If you just mean that from the side view the outboard points aren't on the half way mark, no that isn't an important effect kinematically.
If you want to look at the effect I recommend wishbone.bas which is available from one of the locost sites.
