Ok, fair point. Jamf Pro collects a lot of information by default, but there's always going to be something someone somewhere will want collected as well. For those, you can either add a new Feature Request to see if Jamf is interested in adding it, or, as I said, just add it as an Extension Attribute. That's kind of what they were created for, since Jamf knew early on they would never be able to satisfy everyone's data collection needs.
