I am curious, can you elaborate on this? :) What part of the performance related work involved peeking at the XHR spec so much?

For mapping applications, tiles are loaded to display data. These requests have to be handled carefully, especially when there is a lot of data, because every map movement causes 10s of requests to be fired at once. Their lifecycles have to be managed so they can be cancelled as soon as their result isn't needed (user panned away, or changed zoom level).
I couldn't agree more, and I also think it influenced the standards bodies. New ES[year] specs include lots of very MDN-esque explanations, examples, and "polyfills" for the new features.
For a more nuanced understanding of browser behavior, you have to read the spec. Worked on a high performance network app, and I think I know the XHR spec by heart now.
