Okay, continuing my ask from this original idea:

https://community.airtable.com/t5/product-ideas/proper-revision-history-api/idi-p/153234

I came across this page in the Enterprise Audit Logs:

https://airtable.com/developers/web/api/audit-logs-overview

If you scroll down to the bottom of this page, you'll see this reference:

Which says:

The Audit Log Events API does not reflect changes to contents of cell values. If there is a need to monitor data being placed into cell values of Airtable bases, you may consider using our Data Loss Prevention solution through the Change Events API.

Change Events API?  Data Loss Prevention solution?  Huh?

The corresponding link to that API is currently dead:

https://airtable.com/developers/web/api/change-events

Anyone from Airtable know what's going on here?
