If somebody wanted to learn Desktop GUI programming we wouldn't usually tell them to learn the low level APIs for drawing rectangles on the screen or manually handling keyboard input, we would point them to a framework and widget toolkit for the platform.

The point of a good framework should be to pave over the cracks like double submit bugs, since they are not really things than anybody should be wasting brain cells on.

I disagree on that point. Web development is not the same as Desktop dev. Because HTTP is something you should know if you want to code solid and secure Web applications. If you don't know how it works, you'll end up with forms validated only with JavaScript, double submit because people are loading pages, etc.
