What is Lightroom CC using Lightroom Saved Photos folder for?

I use Lightroom Creative Cloud exclusively these days, and I can't figure out what the purpose of the Lightroom Saved Photos folder is (within my macbook/users/me/pictures folder). If it's an artifact from an earlier version or something, I'd like to delete it because it uses up 4 GB of space, but if it's being used for something, I don't want to cause problems. It almost seems like an error that it exists at all, since, for instance, it contains only one photo (a tiff) from this year (I've taken hundreds of photos), and contains probably hundreds from 2022, which seems random. When I looked at the title of one to see if it exists in the lightroom app, I did find a strangely blank spot in the lightroom library. It contained an item with the title and some settings, but no image appear in that spot. Looking through many of the items in the Lightroom Saved Photos folder, they don't seem to be ones I would've saved, generally, which makes me wonder if these are all deleted items? But I don't want to have to wonder if I'm throwing away some good items, and I don't want to confuse the file structure if the CC app uses this folder for, perhaps, some temporary purpose? I'd feel more confident throwing away the entire folder if it weren't for that single photo from this year, which makes me feel like it is, in fact, part of some internal functionality that I'm unaware of? Can someone shed some light?
