Personally, I think that part is just incomplete. I think that there is an attitude that because you have jumped into several older open source projects and successfully made meaningful changes, that you have mastered the art of diving into legacy codebases and can handle anything. Even if those projects were not all that large. People sometimes think that because in theory thousands of people could be looking at the code, that they can treat the code as if it has been vetted over time by thousands of people. But I agree that there are absolutely eligible open source codebases that could be used to practice beforehand. I'd better; I work on Firefox. It is not a small thing to dive into, but people successfully do, and get solid experience from it.
