Hi Holger, [This comes after reading your message, feeling unhappy about it, sleeping on it and re-reading it again.]
While I see a few interesting related points and questions in your message, I still don't understand what is your position wrt. what's most relevant here IMO, so I figured I would ask you instead of arguing based on wrong assumptions: Fundamentally, do you disagree with the main point this bug report is about i.e. "Should not be part of Stretch"? And if you indeed do want to see this package in Stretch, how do you plan to be involved on maintaining it via stable-security or stable-updates? Cheers, -- intrigeri
