Symbols that user-code puts into the registry do not serialize this way, 
so why should the well-known ones?

If you want to write a JSON helper-pair (toJSON or a replacer, with a 
correponding reviver, I think), then you can indeed serialize and 
deserialize symbols. But there's no ES6 backstage default-wiring from 
JSON to Symbol.for/keyFor.
