I once worked on a feature that apparently lots of clients were asking for. It took 4 weeks to implement. Went to production. Never heard anything of it. 2 years later if we could modify the feature to work for another usecase. I looked at the database. The feature had never... ever... been used.... rows returned = 0
That's why its important not to believe what customers and product managers say what features they want. I have had a ton of occasions where it turned out that what they really wanted was totally different from what the devs were told.
Yeah, I always ask our user stories to have a 'background' section explaining the problem and reason for the feature request so it can help us understand the importance and purpose of the feature.
