We, for instance, structure all our code very carefully with clearly defined and documented interfaces and modularised functional areas. I doubt that any function is really interdependent with more that 20 other functions, never mind thousands. If someone needs to understand thousands of functions to maintain any piece of code then that code has a serious problem and probably a low 'bus factor' (how many developers being hit by a bus it would take to derail your project). I suspect that the power of the lisps tempts developers into writing code that does effectively have many interdependent functions, though they may not fully realise until it's too late.
