I think that's what the parent is referring to (from the wikipedia page they are in L1). Of course that does require the active orbital stabilization also described (though not as around L1). Being closer to the sun is a big advantage, but also impulse heavy to get there. Perhaps an initial lift up to an unshadowed low earth orbit could boot strap a solar ion/sail to get them to L1?
