With fix for #2968, Jackson 2.15 and later 2.x will allow deserialization of certain polymorphic types even if the type id is missing -- as long as target type itself would not be considered polymorphic (is above base type, has no @JsonTypeInfo / would not enable Default Typing).

Unfortunately, due to major refactoring of polymorphic type handling, the fix could not be directly ported in main for Jackson 3.0.
So a different fix is needed here.

Was able to find the replacement quite easily in the end. :)
