> Do you actually use that? Maybe it's just because I have few photos
I use it all the time.
I wanted to recommend to a friend a restaurant I'd visited in San Diego, I couldn't remember the name of it but I knew I'd taken a picture of the food there.
"Food San Diego" and all my food pictures from my trip to San Diego pop up. Tap more info, boom, map appears with the restaurant name on it.
If I wanted to remember what year I went to San Diego, well, I'd either search in Google Photos, or in my timeline on Google Maps. (which is another way to find the name of the restaurant!)
