Make Property Export Data Available via API

The data available when exporting object properties is really useful to audit portal health. I am developing a tool which will run an audit automatically, however the data points for individual properties e.g. fill rate, last update time, and usage metrics are not available via API - to get this data at the moment the system needs to chekc each property individually across all records, but the data exists in the export. Having this data accessibel via API would be great for this tool, and generally to just help audit portal health
