Is your feature request related to a problem? Please describe.
The separation between the domain and the application is broken in several places.
Several objects have a Converter class that acts as a factory. The problem is that this class also is able to create business level objects. Thus these can be created from the application layer and are partially used there.
Describe the solution you'd like
Remove all business level factory methods from this class and separate it into another (protected?) factory class if needed.
Describe alternatives you've considered
Remove the Converter classes from the application layer.
