From helping non-technical family members find where they've mislaid files (such as behind another file on the desktop, which can happen if you drag more than one file at a time) I am confident there is a user base for this kind of thing.
We are, after all, in a world where the youth don't seem to understand file systems and folders [1] and rely on the search feature for everything. Recall could, if done properly, be a great user experience for such people.
It was through user studies that we got both the ribbon interface (great for new users apparently, even if less so for experts) and the fact that when you open an office app it suggests a list of documents you worked on most recently. Sharepoint even takes this further in organisations and suggests documents shared by others that "might be relevant to you" based on what you worked on recently (it's not very good).
If I want to be really snarky, I could mention that UNIX had "Recall" back in the days of text-mode only consoles. It was called the `.bash_history` file, and it's genuinely useful.
I think this was done on purpose to disempower the user.
Google Photos' search bar would be able to complete this search, since like 2015. Recall is completely overkill for this, like building a Death Star to swat a fly.
OneDrive doesn't have those problems, but its search is even more unreliable than that in Google Photos.
In both cases, the companies go out of their way to remove any controls over classification, or even user agency in search. Like, how hard would it be to list all of the categories it knows for users to browse, as well as on the photo page for users to know all the buckets the photos land in? They go out of their way to not do that.
Not that there are any better alternatives. For example, Samsung gallery app is just as bad, despite running locally on your phone, and on top of that, has data loss issues that the company refuses to admit or fix. For some reason, tech companies managed to fuck up something as basic as a photo gallery.
I use bash history all the time, I use my browser history all the time.
To be able to use an OS history would be amazing.
What was the name of the esoteric software i was using to program my lego robot,
What was I working on last Thursday so I can fill out the government required SHRED report to get the Canadian RnD tax rebate.
What was the song i was listening to that Spotify played last Tuesday afternoon.
There are so many times i'd use a feature like this.
You'd need some API for applications to signal to Recall "the user has requested not to save this", and then every single program with a password input box would have to update to call this.
Yea it has stuff for these use cases.

How would the OS have any chance of knowing I don't want my programming session recorded if I don't' tell it?
How would google chrome know to go to incognito mode if I don't tell it?
Of course the burden for this is on the user, what other way could possibly work?
Or for example, you were reading some article but did not save it and now want to recall it.
Or maybe you watched some music clip or song on the some website and forgot the link to website.
A lot of use cases.
