Is that a fault of Rails though or Github's architecture as a whole? In my opinion, Github is the result of hundreds (thousands?) of devs working on one product with little discussion across the entire project. Their HTML patching solution works great in isolation for one team shipping features to their island of the product. But we as users see it fall short at scale. Like you mentioned, things getting out of sync is a real pain point that doesn't have an obvious fix when you have so many people touching the product daily.
