I agree with the overall message of the post but not the analysis behind it. It depends completely on the codebase and where you as an engineer are assigned to work in that codebase. There's so many potential ways for bias to be introduced into that kind of analysis (e.g., what if I am a junior dev assigned to copy edits to the static sections of the website?). There's a qualitative perspective to commits that's going completely ignored in this post.
