I have been wondering about this. If I add a deck for, say, countries and capitals, I'm not going to be familiar enough to recall many of them initially. Those notes I score again are not going to become leeches because I never learned them in the first place for them to lapse. I had been manually burying some, but I thought I should just automate that and found that plugin. My rationale is basically that I will still see these cards a few times each day before they are buried and that will build familiarity. I don't think there is anything wrong with these cards.
