Not at all, JS always allowed a unique object to be made as a guaranteed 
sentinel. That was a feature, and of course typeof sentinel == "object".

I think this is too philosophical a discussion to result in a strong 
reason to risk "symbol". Just my gut-check. Other TC39ers should weigh 
in (Andreas R. especially).
