In fact, even for the `wikimedium10m` case, benefits are apparent for
broader matches. The improvements are modest, but demonstrable even for these
generic cases. And again, in general slower queries tend to benefit more, so
the difference would be more perceptible to users than the percentages might
indicate.
Below are the relevant tasks excerpted from another complete run of
`wikimedium10m` against 1f8c07553fad332d10213a0d506aa8f0a1eae24e (ran an
instance of all tasks, redacted non-Prefix, non-PKLookup from results pasted
here):
