You might be missing the point. A hospital in which surgeries are performed should hopefully already contain all dependencies required for a surgery. So when a new surgery is starting, the hospital staff should not need to run out and get more supplies.
In the same way, the "dependencies" required to build my hardware aren't counted in that number. What counts is the extra stuff that isn't already part of the running system.
