you realize i'm talking about code I have to write, right? If anything, you've further proven my point, considering that the jQuery implementation also covers other common use cases like failure, cross-browser requests, etc., i.e. hours upon hours of googling and/or just copy-pasting the jQuery source into my app, which adds loading time to my site instead of just using a cached version of jQuery that almost everyone already has in the cache in the first place.
