I would hope so - I still come across Windows 3.11 machines connected to specific, very expensive, hardware, running software that would not run under a newer OS. I dread to think what would happen if any of those machines needed a reinstall and some form of activation was required, but there were no activation server any more. That could be several grands worth of badly needed hardware down the pan.
(The hardware I'm referring to here are mainly things such as scientific instruments and engineering equipment such as CAM machines.)
