What we can achieve by putting MonoBehaviour inside namespaces?

Hey guys! As everyone, I'm really excited about Unity 4 coming out in some weeks(or days, maybe..?!). I took a look in the release notes and I found out an interesting update(well, I think it is...): *Scripting: MonoBehaviours can now be inside namespaces.* I want to know what we can achieve by putting MonoBehaviour classes inside namespaces. I'm not a big user of namespaces, so I really don't know much about it. Our classes will not need to directly derive from MonoBehaviour if some namespace which contains a class that derive from MonoBehaviour is being used? Thanks from now!
