@Robert: is ppa-purge designed to only "downgrade packages that exist in another rep" ? what is the expected behavior if the removed PPA has a package that is not present in other reps (like in this bug report) ?
@Percherie: concerning your suggestion to add an option to "delete PPA" instead of "comment PPA", you should fill a new "wishlist" bug report.
