Hello Jeroen,

this looks like it's very well done. Thank you. I just have a few
little suggestion.

 review approve

Cheers,
Henning

I don't know if you like lambdas but they are not banned anymore
AFAIK. So this could be written as:

    return filter(
        distribution.all_distro_archives,
        lambda archive: archive.purpose in ARCHIVES_TO_PUBLISH)

But I let you decide what you find more readable. I personally do not
prefer the dangling if clause.

Should the script not say something if this list is empty? Or even
refuse to start?

This is a Good Place for the MatchesStructure matcher from testtools.
