Think about fields with multiple values

For example, this UI:

ui-example.mp4

And on the server that's validated like this: https://github.com/kentcdodds/fakebooks-remix/blob/15daa8e1c76a87df7f2af044d9b710d071c2a1f2/app/routes/__app/sales/invoices/new.tsx#L79-L93

I wonder how that would look with validity-state 🤔

From a UI standpoint, this sort of "just works" since useValidatedInput is scoped to a given input, and IDs are now unique via useId. I think where this will break at the moment is server-side validation since we're probably not doing anything with formData.getAll so we're probably only validating the last of each duplicate input.
