We also need to make sure that we react to a test fail in that area, as

That would certainly simplify the job of packagers, who could subscribe
to changes in that repo and throw their weight in the discussion when a

the per-project requirements ? Would this approach have protected us
from the recent setuptools upgrade issue ?
