Existing Groovy methods will not be removed immediately.

## Status

ACCEPTED

## Consequences

* If we would have used `Closure`, we must instead use `Action<T>`, `Spec<T>`, `Callable<T>`, or `Transformer<OUT, IN>`.
* We need to ensure all APIs that are exposed in the Groovy DSL go through runtime decoration.
