I thought coding conventions prevented advising primitives?
I does not look clean to advise `require' here, just for Org.

I don't understand why we need this.  

This is at best a workaround to fix dirty installations.

I updated Org's installation process yesterday:

  http://orgmode.org/org.html#Installation

I made it clear that the user, if she wants to install Org on top of
the pre-bundled version, must choose between on of the three methods.
For each method, I explain how to set up the load-path (if needed) and
org.el will load the correct org-loaddefs.el, resetting autoloads
correctly.

In org.el, no Org package is required before org-loaddefs.el is loaded.

I don't see why this should happen.  Setting the correct load-paths is
the first thing user should do in their .emacs.el.
