I really think we want to align all APIs here. Having sendBeacon,
WebSockets and XHR all do different things seems like a bad idea to
me. Especially for authors, but also for spec authors and

I personally think C makes the most sense since it doesn't involve
grabbing some omnious global state. Instead the behavior is determined
by the more tangible answer to the question "which object did you call
a function on".
