Package managing can be sometimes difficult to deal for an automated 
routine and more that often needs human interaction.

For instance, by default ppa-purge (or a similar script) is instructed to 
remove non official versions of the packages in favor of the ones 
available in Debian repositories. Fine, but reverting ffmpeg from D-M to 
the official version it can be undesiderable or even break based on the 
current pining and priorities (it can leave your system with mixed 
libraries from differenet sources).

I, personally, don't like playing much with this (packaging and 
libraries). In the event I have to, I prefer to see and manually cherry 
pick what to keep or what to upgrade/downgrade case by case.
