IMO, if the rust can be minimized, I think a repaint would be worse than letting the rust bloom in the first place. Losing paint that was applied by the maker himself would be a sad thing. That said, we haven't seen detail photos of the rust. Side note, but I would remove that tape from the top tube. It's probably holding in moisture.
You can try OA or Evaporust by dipping a bit of paper towel in the stuff and then applying it to some place inconspicuous like under the chain stay an then wrap it in saran wrap to keep it moist for the duration of the instructed treatment time. If you are considering a repaint anyways, you have nothing to lose.
