Thanks Ewoud and Dirk.
Happy to hear that this blocker will be resolved with Foreman 3.4 if I understand this correctly: The foreman-maintain 1.1.3 is now available on Debian! & Tracker #34194: Foreman Maintain support on Debian - Foreman Maintain - Foreman
regarding “last round of QA”: I am unsure what you mean exactly, but as said before, downstream is already using the docs & we are heavily improving, adding, fixing, and extending stuff; there’s a lot of activity in foreman-documentation right now.
