The *.proto files still remain in "google/protobuf/" and conflict with the ones coming from the real protobuf jar that I get through various other dependencies I have (I get protostream through infinispan-core which recently added a dependency on protostream it seems).

Is shading protobuf really required ? Protobuf retro compatibility seems good so simply having it as regular Maven dependency instead of partially shading it would make dependency handling much easier for me.
