I've just updated the todolist for the unneeded python2 module removal
with data from archweb since the list lacked a lot of packages.

Everyone who has archweb with all repos importd can run the following to
get a list of packages which require python2 but aren't required by
anything else.

from main.models import Package

pkg = Package.objects.filter(pkgname='python2').first()
for repopkg in pkg.get_requiredby():
    if not repopkg.pkg.get_requiredby():
        print(repopkg.pkg)
