How to make Report implementation Serializable

The Report interface extends Serializable, however, even official implementations like SimpleReport aren’t Serializable.

Are we going to make Property serializable in the near future?
Or, can I simply ignore the fact that the Report interface extends Serializable? At least the reporting task seems working well.

For your reference, my Report implementation is here. I know how to remove Task field, but not sure how I can remove Property. Thanks for your help in advance!
