While this is the nicest solution so far, it requires some telepathic view
into the future. At the time you depend on a package's API, you don't know
when it will break BC. And for this idea to work all package already must
have this dependency entries. So you not only have to be able to look into
the future, you also have to be able to change the past. ;-)
