------------------------------------------
I think this ticket can be postponed until it is needed, since the mechanism
with *any()* will have to be redone.
> "Any" listeners do not get notified for subclass-specific keys in Polymorphic

> Polymorphic configuration allows having multiple inheritors of a base schema.
> There also exists a feature that allows to add listeners for changes to "any"
> configuration keys. This is implemented using a dummy configuration inside
> the generated classes, where all such listeners get registered. However, this
> does not work for Polymorphic schemas, because there's no way to know the
> full set of configuration keys in advance, since the actual type of a
> Polymorphic configuration instance is not known at the start. This leads to a
> limitation: changes to subclass-specific keys are not propagated to "any"
> listeners.
