Brion-
Maybe, but you wild still have to solve the problem of showing all linked debates on the page.
No, because that's not a problem that needs to be solved. Most of these "debates" won't have changed at any given time, and showing them all makes it very very difficult to work through what's going on.
When I go to VfD, I check for debates that are unusually long, or vere heterogenous (many deletes, many keeps). So I systematically search for controversial pages to see if any issue needs to be clarified. Others will likely search for pages where they can add "Me too" votes to seal the deal, etc. This kind of systematic browsing of VfD, as a matter of housekeeping, is only possible if all debates are visible on one page.
