> Currently, polymorphic configuration schemas must have exactly one parent
> class (not Object).
> It is suggested to implement the following logic:
> # Top config schema must be annotated with PolymorphicConfig (it already
> works as described here, so nothing needs to be done)
> # Leaf config schema must be annotated with PolymorphicConfigInstance (it
> already works as described here, so nothing needs to be done)
> # Intermediary config schema classes (extending, directly or indirectly, the
> top config schema and extended, directly or indirectly by leaf config
> schemas) are allowed. They do not need to be annotated.
