On October 2nd, Apple posted a news article on developer.apple.com, stating that:

Some developers are using Full Disk Access in ways that could put users at risk, exposing everything on their systems—including files, mail, messages, and even browsing history—without users’ full knowledge and understanding.

And:

Going forward, we will introduce additional controls to ensure that users who genuinely wish to grant an app this extraordinary level of access can only do so with very explicit user action. 

This has been posted on a few places, but I just wanted to post in case folks have missed it.

If you’re a Mac Admin, you’ll need to keep an eye on this and any changes. I’d also urge you to file feedback on this, with many fellow Mac Admins having already submitted feedback and posting it to the #apple-feedback MacAdmins Slack channel too.
