Agree no one is going to downgrade but there is another strategy - always build your app against package versions that is in Debian stable. Of-course it can be problematic but have some advantages: well tested, any bugs probably have documented workaround.

Yep that was my take on it as well. Vendors should be able to test their software against a vanilla install of debian stable and build the deb package themselves, and then upload to the package repository for review. Else, the vendor provides instructions/support on their external website.
