Feature request: `FormData` about components

[hollg]

What's the use case for this component? My understanding was that this pattern is used when your submit button immediately fires a POST request, but our Form doesn't do that — we can do anything we like with our collected data inside the onSubmit function, including adding other data to it.

@hollg You're absolutely right, I was trying to replicate a utility that's now redundant 👍
