Very much not a new idea: https://en.wikipedia.org/wiki/Very_low_Earth_orbit

Though fun to see. More interesting than the station keeping (indefinite part) is that it enables ~100km orbits, which are ~5x closer than what remote sensing satellites use today and thus could get 5x the resolution for the same instrument.

Yes, the article also points out that the idea is not new, but rather that this research was focused on addressing practical problems, such as corrosion of the engine's parts.
