I understand the desire for the deb-multimedia repo, but this would make for a major change in the import structure.
Although it is dealing with wheezy and therefore import compatible packages supporting 11 archetectures, and I can begin to picture a routine that would not cost everyone in terms of import performance, only those who choose to add the repo. But it is beyond the scope for now at this stage in testing I think I am safe to say. For now at least. :-)
