I only remember Dave briefly mentioning it as one of the potential ways to get a wrapper object; I don't remember a decision to prohibit it.

On the other hand, this is somewhat attractive, as it prevents getting a symbol wrapper object except inside sloppy-mode methods/accessors added to `Symbol.prototype`, wherein `this` is a wrapper. Which means, unless I missed a case, that in strict mode it is impossible to create a symbol wrapper object.
