Description

At the moment, MapDeserializer throws an error if the key for the Map is not a String. Can we add a feature to allow the JSONConfig to have a custom deserializer for the Key, like in Jackson? Or Can we extend the Deserializer framework to allow registering custom Deserializers for a Map? At the moment, Deserializers can be registered for other datatypes through Adapters but not for a Map.

Research direction

Start by tracing MapDeserializer and reviewing how JSONConfig and Adapters currently register deserializers. Clarify with maintainers whether custom key deserializers, custom Map deserializers, or both are required; the work is complete when the agreed approach supports non-String Map keys and is covered by appropriate tests.
