I guess the question is what is the point of the popcon statistics.
Insofar as they're used to determine defaults, skewing them toward

popcon is a really bad way to determine defaults because it is so
heavily skewed by existing defaults.

More useful uses of popcon include: estimating the downside, if some
package is (or may become) broken or removed; and, maybe, estimating
the user preferences between different non-default leaf packages.

For me, if I were doing (say) RC bugfixing and was considering asking
for a removal, even a moderate popcon figure would give me pause.
Conversely, a low popcon figure would encourage me to consult on
removing the package.

I don't think popcon is a good reason to pause if there are valid concerns suggesting removal is a good thing, for the exact reason that it's skewed to propagating existing practice. I'm not sure there's any really good use for popcon, but I'll continue to believe that any value it does have is more related to how many unique configurations it reflects rather than how many duplicate instances it can hold.
