Marc, would not assumptions for a Festool shop differ considerably? Far fewer big machines, and more carrying lightweight precision machines to the wood, for example. I only have a few Festool machines so far (took quite a while to get past the sticker shock), but I am beginning to see how it could change the way we work. My 400 sq ft shop is getting awfully crowded with floor-standing machines and implementing your guidelines, sound as they are, is difficult.
Unless you’re a big fan of frequent shop remodeling, planning the layout of your workshop early in its development will save you a lot of time and trouble and also can keep you from spending years in an uncomfortable, poorly organized space. And if you already work in a shop that’s as organized as a trailer park after a tornado, careful planning and a little remodeling is likely to help you make a quantum leap.
