Sadly, there is a very good reason we wrote a new, stand-alone installer/upgrader for ownCloud 9.0: the code IS intertwined in older versions and that thus means what the Debian developers wanted to do is something most of us wouldn't dare to try ourselves. Now you can say "what do ownCloud developers know of upgrading ownCloud" but... ;-)
If you were right and things weren't so bleak, we would not be unhappy with their attempt to do this - we'd support it. Realize that we're talking about upgrading ownCloud 7, 8,0, 8.1 and 8.2 - relatively old code. If they wanted to make it possible to skip releases starting, say, ownCloud 9.1 I think we'd say "go for it", as we now have a self-contained upgrade routine.
