Thanks for the suggestion. I forgot to mention hierarchy_stoplist, but I had
considered it. It seemed messy/imprecise, since it matches anywhere in the
requested URL, but in general that wouldn't be a problem. I'll wait and see
what other people suggest - and whether there's a difference between what
people are doing in reality and what people familiar with the implementation
of the different possibilities would recommend based on relative efficiency,
if the differences are enough to be worth considering.
