The meaning of this profile would be muddled at best.

Let's think about when this issue would pop up. We've seen it here, with a very large simulation with many haloes. In this case, the only time you're interested in the profile of the small haloes is for statistics, like me. If you're trying to do anything more with them you've done the wrong sim. And since I'm just doing statistics, throwing out bad ones, or having a few junky values, won't change things. What other cases can we think of where this would be an issue?
