Right, a debian package by itself does not mean anything. What is
important is that, at an instant t, the debian archive strives to be a
self-consistent set of packages, that all build and run together, with
known relationship.

I think that one thing that contributes a lot to the quality of debian
packages (real ones, not fink, I don't know for fink) is that, under
Debian and Ubuntu, they are built is isolated environments. That way no
build or installation side effects creep in. Making a Debian package for
your soft is a great way to make sure that it really builds, 100% of the
time, because if it doesn't, one of the different build bots will find it
for you.

That culture is totally absent from Python packaging.
