There are many use cases for using Custom Data Discovery Records (DDR) to help drive automated workflows and categorization of systems for collection queries, etc.

While we can do this automatically from Active Directory thru discovery, we don't have a similar mechanism for workgroup or AAD systems.

Having the ability to Import/Update as well as Remove custom DDR data programmatically enables more complex workflows an integration points to retrieve data out of external IT Service Management solutions to drive business processes while avoiding the use of Direct Collection Memberships.
