It is good to recognize the impact of this, however, I would suggest
that if having open changes that are not "actively being worked" is a
problem for statistics, let's change the statistics calculation.  Please
do not abandon the work of contributors to improve the appearance of
these metrics.  Instead, simply decide what criteria you think should
apply and exclude those changes from your calculations.
