for a start, the ability to partition that knowledge?
e.g. what is being researched or worked on for project A, might be vastly different or require different domain of knowledge for project B.
Or worse still, you ended up reusing code across different projects for different clients, and one day client O(#1) decides to sue client G(#2) and finds code similarities?
[1] as example, perhaps client O has a name that rhymes with "Horrible"
[2] and potentially client G's name rhymes with "Flugel"
