validationError with custom action data

[thomasverleye]

In my current use case it would be great to return a validationError with some extra data.

The endpoint I'm using returns possibly some extra error messages which cannot be mapped onto any fields.
Consider following example:

export const action: ActionFunction = async ({ request }) => {
  const formData = await request.formData();
  const fields = parseFormDataToObject(formData);
  const { data, error } = await validator.validate(formData);
  if (error) {
    return validationError(error, fields);
  }
  
  const { apiData, apiError } = await someApiEndpoint(data);
  if (apiError) {
    return json({apiError}, {status:400});
  }
  return json({});

Currently, if a user isn't using JS, this means the form will be cleared when an api error occurs.
I know this is an edge case but this edge case happens more then expected.

So it would be awesome to have a the ability to add extra data to the validationError function :-)
