Quoting Chris Lamb <lamby@debian.org>:
In many cases, there is an issue open about the new binary package(In my experience, there is not.)When there is no bug report open at all, well, bad luck.Well, possbibly, but if one is investing time and effort in changing a process it seems a shame not to cover these cases IMHO. :)
True. Proposal: Maintainer should make sure they have a bug open about any new binary packages and close them with the upload. If they forget this "goto badluck;".
