There is no such thing as 'mint-specific' packages. It's just the Ubuntu repository, with a different default installation and some 'out-of-repository' settings, script and GUI applications. Mint is not a build target in any way shape or form. Ubuntu however, deviates enough from Debian (patched kernel, patched/out-of-sync glibc, as well as patched core libraries) that one would have to explicitely test on Debian proper. To call these packages Mint specific is like calling the windows executable HP-Windows-Executable, because you had HP crapware preinstalled.
