Description

Currently (1.9.0) Module.SetupContext only has accessor method for getting SerializationConfig/DeserializationConfig instances. This allows changing of feature settings currently; but due to plans to make these objects immutable (and replace setters with withXxx() fluent constructors) this will not work in future.
But there aren't alternative non-deprecated modification methods available yet.

Solved this problem bit differently: added

Module.SetupContext

{ public ObjectCodec getOwner(); }

which gives full (unsafe!) access to mapper itself; this way brave modules can try to actually modify state of ObjectMapper itself, including modifying features.

Modules are discouraged to do this – all intended access should be via safe methods – but this fallback should allow workarounds in wide variety of cases, including that of changing feature states.
