Err, ... it is about libraries, not applications. And the idea is to
bump the virtual provide version when an incompatibility is added. I
know you will know that the current version is source compatible with
the previous one, but how can you now it will be source compatible with
the next version ?
Also, i am not entirely sure that source compatibility is enough in this
case, not sure though.
Anyway, the idea is to make it mandatory for the case where it will
break things not having it.
