Are we here just moving deps one line lower?

In the AOSP commit they are switching from
@com_google_protobuf//:protobuf_java
to
@maven//:com.google.protobuf.protobuf-java
but they both map to
@protobuf//:protobuf_java
see

Yes, I've check the original commit already, I was just wondering if this change is a good idea, if it doesn't provide any value. But lets have it for consistency sake
