Instead, the new proposal is that SharedArrayBuffer passed to postMessage to a DedicatedWorker will share it regardless of whether or not it's in the transfer list, while if it's passed to any other kind of cloner, it's cloned.
Weird, but that's what's being requested.

That's not quite what the model we ended up with in https://github.com/whatwg/html/pull/2518. If it's in the transfer list you get an exception, and if it gets to an agent you cannot share with that agent gets an error.
