I hear you. There are too many dependencies to even dig into each of them, or even one of them. On the other hand, it could start a journey to contributing if the fix is small enough and picqued your curiosity (time notwithstanding). One (suboptimal) approach is to put one's foot down and say, "Okay, from here I will only allow my own tools to express my understanding, and nothing else is allowed." So begins a tree of infinite prerequisites, and we become frozen at the first step of a million leaves. At least, we have enough source code to embark on any number of expeditions. Practically speaking, I understand the desire is to build upwards versus reflecting below.
