Annotations and managed beans declarations in faces-config.xml

Question

I get JSF 2.0 and doubt the new annotation-based auto-signature (declaring managed beans without any code in faces-config.xml).

As far as I know, this is wonderful and easy, but the problem may arise with a certain need to replace one bean with another in a large system, which, if annotations were used, would lead to the need to delete certain classes (or a similar dirty hack), while it can be easily fixed in faces-cofig.xml.

Please share your experience on this. What should be considered more convenient and why?
