Thanks for this. I probably won't be reading this before other topics, but I've often found that changes from google were lacking the backstory to make sense of them as a coherent whole. For example, a patch that says "Instead of detaching at the commit recorded in the superproject, check out the branch with the same name, even if it points at a different commit. Here is the write up of what it does in the Documentation/ and code" is hard to judge beyond checking if the code does what it claims to do and if the docs describe what the code does---without backstory like this that talks about how individual small pieces fit within the plan for the whole thing, judging if that "what it claims to do" is even sensible is impossible.
