It’s clearly meant for a commercial or a funded setting. As a hobbyist even if you have a bunch of SBC’s you need flashed like if you are building a Pie cluster for some reason or you have a bunch of them for automation you still would only do this once, so it taking 10min or an hour isn’t a big deal.

If you are pumping out 100’s or 1000’s of these a week yet alone a day you are probably making money of it or supporting an activity that does.
