Apple Photos has fallen into this trap as well.

As a user, you have no way to see if a photo has been "scanned" with smart features and what it has detected (e,g found person x, found dog, blue sky, beach etc).

Trips features, has this algorithm finished scanning your library? You have no idea, it's just hidden.

Faces, detection, has this completely scanned your library? You don't know. Photos that don't seem to have faces detect, was it scanned or failed or did it not scan yet?

The list is nearly endless - but in line with the rest of the direction of MacOS, getting worse.
