I haven’t done any particular clean-up for my thunderbird upload, from an sbuild stretch chroot on stretch, and that upload was processed just fine. So I think 09824d3cd53b06c15af7f4c80b5c7c53966b7908 is right and we could update the documentation to strip those bits entirely?

On the infra side, it might make sense to get rid of .buildinfo and .udeb files though, as part of some clean-up?

Filing this as contributors documentation, without categorizing as infra as it’s a bit of a dual bug report (infra & doc)…
