This will not return the default value is `include-defaults` is `true` and `statistics-enabled` is not defined.

Something like this covers this case:

                  final ModelNode seValue;
                 final ModelNode includeDefaults = operation.get(INCLUDE_DEFAULTS);
                 if (includeDefaults.isDefined() && includeDefaults.asBoolean()) {
                     seValue = CommonAttributes.STATISTICS_ENABLED.resolveModelAttribute(context, model);
                 } else {
                     seValue = model.get(CommonAttributes.STATISTICS_ENABLED.getName());
                 }
                 context.getResult().set(seValue);
