This is a recipe for disaster since the dependencies will likely break ABI
at some point. Then our package will FTBFS if we are lucky, or build and
run with the wrong version and give very interesting bugs later on. (On the
other hand it's similar to what we already do...)

It seems to me that we must keep track of ABI compatibility. This is a bit
complicated, but it's our job if we want to be a well-integrated
distribution. In other words we should try to solve the library versioning
problem first, and only then try to build packages with Maven.
