This will break the final look of the component configured with caption or captionIcon props. Since we don't use this default spacing between caption text and Input field, a user will more likely have to apply it on his own. Which makes Eva not Eva.

Instead, I would suggest removing the captionIcon property and wrap the entire caption element in FalsyFC or better FalsyText so we can remove the caption container view. This way of composing elements will allow us reducing useless spacings between components.
