If a Task Form is removed will it still show in Reports?

Q: If we have an old checklist that isn't needed any longer, and it is removed, what will happen to the old reports? Will that information become inaccessible?

A: If a Task Rule is Removed from a Task Form, the completed Tasks Task Form Elements stay intact in the report.

If an Element is Removed from a Task Form - the reports stay intact.

If an Element is Deleted altogether, the reports no longer show that Element.
