That is about as compact as default handlers allow, with one minor
difference: you could use `MINIMAL_CLASS`
instead of `CLASS` to likely further reduce class name portion.
There is no out-of-the-box mechanism for associating polymorphic type
to container, however; for that you would
need custom deserializer (or perhaps in theory custom `TypeSerializer`
/ `TypeDeserializer`, but probably not worth
the hassle over custom (de)serializer.
So I would probably just write custom `JsonSerializer` /
`JsonDeserializer` pair if compactness is very important.
