I would assume that any legitimate usage of this function would be heavily marketed as a time-saving measure, something like:
"Many of our customers prefer to start off with a fresh install of Windows. We understand that hunting down drivers just to get hardware working after a reinstall is frustrating and time consuming. Now, we're using cutting-edge technology to ensure your computer has a direct line to automatically download the latest drivers even after a complete reinstall of Windows! System administrators: If you'd rather have a completely blank slate upon reinstallation, this option can be disabled in the BIOS."
You don't just spend time and money getting a feature like this set up without some sort of return on your investment, and in an ideal world this would actually be a pretty decent selling point. I would love to be able to do a fresh install without worrying about driver downloads & updates immediately afterwards. It's not a huge thing but it would be nice.
In contrast, Lenovo's implementation got shut down by Microsoft, and was only discovered by someone doing some deep diving into their own system. Otherwise it would have quietly been a thing until they had to patch it out. It was also difficult to disable, implying Lenovo didn't plan on allowing it to be disabled.
