Definitely needs more thought! This is based off data generated by David Golden, which lists all dists and the total number of downstream dependencies each dist has.

When doing dev releases of dists that are "up the river", look for changes in the CPAN Testers results of downstream dists to see if you've had a knock-on effect. This could be automated in a 'river smoke tester'.
