I think you're mainly thinking of machine learning and data science applications, and so your perspective may be a bit limited. But, of course, you didn't actually give any explanation of what you mean other than mentioning ordinary least squares. Would you like to elaborate and back your point up?
In computational science and engineering, there are many applications in which the SVD is a very reasonable and good choice. Some examples: fast direct solvers for integral equations, model order reduction, solving inverse problems, etc.
