For building a more complete picture of how fields are being used within a company, it would be nice to be able to export over the API some additional details of the record properties.
In the user interface you can see who created a property, if it's connected to lists, forms, workflows and other resources. This would be handy to be able to pull via the API as well to build dynamic data dictionaries eg. by pushing field information from multiple systems to a Google sheet which can be used to review the need for the fields.
One other thing could be to include the calculation of how many records have a value in the field vs don't.
