Security nightmare aside, it seems like it would be handy all the time. Surely everyone has had trouble finding a website or document or email again, days or weeks later?
Documents and emails are probably easier to find via old-school text searching, though.
What if you don't know where it was though? What if you saw a bit of text, but don't remember if it was in outlook, confluence (if so, which), mattermost (if so, which server), or teams (maybe a screen share?). Those are all systems I use at work, and while I've never been quite that lost about where to start, it's also not wildly exaggerated.
Most or indeed all of that doesn't need screen-scraping though.
