The big downside of usuing these cookies to inject my configuration into the loading of a package is that it means that I can't load that package without my configuration anymore. This means that when I start ‘emacs -Q’ and then call ‘package-initialize’ it'll load my configuration as well. This makes debugging things very difficult.
