I think a look at the “wire protocols” used in remote debugging might get you closer to the elegant minima than looks at WinDbg, because WinDbg has evolved a bit in response to customer demands, which generally revolve around making one or two things super easy, at the expense of any fundemental improvements in understanding. When it comes time to serialize/deserialize/synchronize representations across a boundary, simplicity is paramount - who wants to worry about what version of the debugger stub somebody has, when you can break down a task into simple steps and not have to reinstall or freak out.

My guess is that God likes version control managment for the same reasons we do.
