That sounds like a plan.

Indeed. But testing that the packages install, upgrade, remove and purge 
correctly on top of the previous versions from unstable is already a good 
indicator.

Indeed, didn't think of that use-case.

The .changes file doesn't have the arch:all packages, but they might indeed be 
dependencies of binary packages. I suspect that the fact that buildds have 
access to incoming.debian.org could facilitate this step though.

Sure. I just tried the --run-piuparts option of sbuild on on of my packages 
(lsb) and it failed miserably for that very reason.
