I'm pretty sure that a bigger factor in why secure facilities have limitations on windows (and especially on ground floor windows) is physical security.
Not really. Non-operator windows do not degrade physical security that much, or really at all if they are not accessible from the ground. It is primarily danger of surveillance that drives the lack of windows.
