Can we fold into this ticket the behavior shown in this screenshot? Specifically we're looking for an ability to show "Uploading..." while the file is uploading. I've looked around here: https://design.va.gov/storybook/?path=/docs/uswds-va-file-input--docs and not found anything that looks quite like what we're looking for. I figured perhaps in addition to name and size we could provide an uploading boolean that would trigger some sort of Uploading... state (like shown in the screenshot here).

@Thrillberg This is not a bad idea, but it's out of scope for this ticket. Please submit a separate request.

Sure thing! Here is another issue: #3660

Ultimate goal of this ticket is to provide a way to show that a file has previously been uploaded, without requiring the file itself. The "name" and "size" props were suggested as a way to 'fill in the blanks' because those values are what are currently available to the developer from the Redux store.

Another option would be to override the existing "value" prop to accept an object (e.g. {name: "File Name", size: "XXkb"}) in addition to a File.
