base-system: what are your plans for stabilizaton of 8.2, what do you think about backporting?

why would any distro care about security issues in the distcheck rule ?  no one runs it, only the person upstream creating the release does.

I'm not into autobuild, so this didn't ring a bell and I thought base-system might use it. Thanks for the elaboration.
