Ergo, more code, much more development time, more chance for bugs, for questionable benefits (there are an endless number of web applications running on Django. If python is fast enough to tell the OS what IO to do, then surely enough Java with two indirect calls (which you will likely end up doing in your hand-written implementation as well) will be more than adequate.

Also, I don't buy that more code is easier to hold in one's head. An annotation that literally declaratively says what that thing is is much easier to grasp and maintain.
