For example we could have a: 1. `SerializerFactory` with multiple implementations each one in a separate module, 2. You use the `ServiceLoaderUtil` to find an implementation or you use the internal one if there are none. I think that the dependency injector is a feature that should stay in 3.0 to motivate people to move from 2.x. Piotr
