It was dropped because I couldn't see a good use for it. You can get  
an array from any RDO object by using $ob->getIterator->getArrayCopy()  
(and this will include relationships, etc.).

What's a small example case of where array access to object properties  
helps you? What does serialization have to do with it (we can just  
exclude mappers from what is serialized in Rdo objects - that's  
probably a good idea anyway).
