Good question. However, this is a far smaller problem than
the one we face now, and any incremental improvement is better than

Maybe. (bbdb needs to be run whenever the status of vm
changes). Hmm. I am not sure how one may reliably fix this, without
an elaborate system of hooks (preferably implemented by
dpkg). However, again. this is a smaller problem.

Right. But changing dpkg has its own problems (like, time
taken to ;-). I think we should go ahead and implement this
functionality, flawed as it may be. And then prior art may be used to
leverage a change in dpkg ;-).
