One interesting aspect is the difference between displaying yourself and others in VR.
For yourself you do not want to show body parts that cannot be tracked correctly because of the jarring effect of the mismatch, as you say. But for showing other people you can get away with more, so for example you can show full arms even if the elbows are not exactly in the right place (as long as they are not unphysical of course.)
