I agree, I would like to see a more general-purpose solution for this.
One problem that we have is that |new FormData(form)| allows
synchronously grabbing, so we'd likely end up having to fire
synchronous callbacks, which is always unfortunate, but I don't see an
alternative here. Especially since grabbing data asynchronously is
always risky.
