This is true, currently the library solution is worse (more 
dangerous and more broken) than the precedent built-in feature. 
But there is hope to have a good solution someday (mixing library 
code and some kind of built-support), while a broken built-in is 
not good. Andrei did the right thing: if you don't have a feature 
it's kind of easy to add something, while fixing some bad 
built-in is rather harder.
