Data export API - Delete PK

Hello,

on the data export API, delete PK feature to export data deleted in the system was originally available only for some transactional tables and later has been extended to the other tables. To be able to perform our tests of data export we would need to know by when the delete has been activated on which table, so we will know that we can't expect to receive a delete before that date.

Is this list of tables including the activation date of the delete feature being available somewhere to be consulted?

Thanks
