In a vacuum chamber there is still the Earth's crust vibration to consider, that affects the object in the vacuum, whether it be optics or whatever. That is why isolation is necessary in a vacuum and also necessary outside a vacuum - to reduce seismic vibration. Your example of footfall affecting the stereo cartridge stylus demonstrates my point quite well, actually. No one is saying acoustic vibration should NOT also be addressed. Or the internal induced vibration, unless you believe motor noise and transformer noise are good things. If you are so enamored of vibration I suggest you consider putting the whole thing up on a shaker table.
