This is the only one I feel is relevant. > * visible to Object.getOwnPropertyNames Symbols are also visible (using getOwnPropertyKeys) > * no way to differentiate a unique string from any other string There is no difference.

Using symbols you would need to use symbol.name. For debuggers and dev tools, they can always special case. But that applies to both. > I'm curious why the desire to not have unique symbols? I was under the impression that private Symbols or relationships or whatever could be punted without affecting unique Symbols, which serve a different use case (name spacing and encapsulation, not security). This proposal covers name spacing while ignoring encapsulation. > > _______________________________________________ > es-discuss mailing list > es-discuss@mozilla.org > https://mail.mozilla.org/listinfo/es-discuss
