The reports stopped once we fixed the debconf variable name problem, so I don't think so.

I suspect it depends. Maybe we could do it based on release rather than version. In squeeze (I intend an LTS upload soon) and in Ubuntu before 15.04 it need never be removed. Ubuntu 15.04 it can always be removed (Ubuntu has never supported multiple init systems).  Maybe then something more careful for wheezy/jessie.
