I'm still trying to understand if it's a good idea to contact upstream authors and tell them their software is being worked on to be included in Debian, or not.
My own experience has been that most upstream projects don't care about Debian.
Some do, of course. But many don't.
With my experience, I realized that saying nothing was a safer bet (sometimes it's really a good idea and most of the time it's not acknowledged, and a few times it's a bad reception).
but it's somewhat disturbing !
That subtlety in contacting upstream is documented somewhere ?
