Well, I would expect that it's possible at some point to deprecate the 
*default* base being Object.

that is, currently you do not have to type your class as:

class C : Object

But you would have to type your ProtoObject based class as:

class C : ProtoObject

We could easily deprecate the default (require people to specify the 
base), and then at some point remove the requirement for ProtoObject.

But I wouldn't expect it to happen for years. Probably after much 
frustration of having to remember the ProtoObject base specification.
