This puts the configuration of the nested mapping into one place (method) where it can be reused from several methods in the upper level,
instead of re-configuring the same things on all of those upper methods.
====
[NOTE]
====
In some cases the `ReportingPolicy` that is going to be used for the generated nested method would be `IGNORE`.
This means that it is possible for MapStruct not to report unmapped target properties in nested mappings.
