One could essentially reverse the Eagle export to KiCad ULP to make one for import. Perhaps there has not been sufficient demand for someone to accomplish this. It seems so many things are available as Eagle libraries and Eagle designs that KiCad users want, with not so much of the reverse situation. Though I've recently learned that CERN is currently working to improve KiCad tool set, and perhaps at some point this comparison may change. I wouldn't hate the idea of going into their new KiCad manual router and back to Eagle again... But fir now, there's not yet very much out there to download and import into Eagle.
