Description

Over the last releases we already started to refactor the injection implementation (constructor, field, reference injection) and use an internal API layer to abstract from the actual implementation.
However, the work is currently only half done, we have interfaces for some parts but directly use implementations for others. We should try to clean this up and have interfaces for everything
