Was that before or after the changes made to the trust system? I'm not on my computer and can't search for the date, but I consider that to be quite relevant, since there used to be no posibility of leaving neutrals.
I would actually argue that it would be
more useful to leave counters after the changes since the trust scores are themselves diluted by the extra members in the DT circle, the pressure to switch to one's own custom list, as well as the entire premise of flags.
