It is typically considered best practise to only give permissions to those that need it. *IF* you can do things without elevated privileges I would argue that we *should*. The real question is what is strictly necessary in these different scenarios? We need to stop thinking strictly with people setting up machines that are completely disconnected from the net, purpose setup for running a house sized machine whose 1-ton gantry is moving at a 0.5m/s. We have people using EMC to run 3D printers, mini mills, laser cutters, etc., off of their desktops, embedded machines (accessible through the web), and maybe even laptops with hardware assist...
