Is there no way to:
1. Have ACF log the data in creates in DB, and then remove based off of log?
2. Have ACF prefix fields / data it creates with something like acf_and then the data or key, etc.
3. Create it’s own table to read / write to?
I think it’s understood that ACF is one of WPs top most used addons / plugins.. those that use it, know this.. I preface my comment saying that because I would gladly create another DB table OR entire DB just for ACF to utilize if it meant the unused data could then be safely removed.
