It's pretty natural, we don't really have anything better that this stack, do we?. If you're writing JIT, why invent your own backend if LLVM is good enough? I mean, well, probably it's possible to write something better than LLVM, but it would be quite exceptional work. And what that section describes would be pretty typical for any duck-typed language passed to LLVM. Devil's in the details, anyway. Actually, at this level of detalization you can say that almost every cooking recipe sounds the same: "Chop products; put them in the cattle and put it on fire for some time; season it".

Many people (including myself) think PyPy is a better stack. We will see.
