They theoretically agree that the material's properties could be nice for making some kind of superconductor, but present no clear indication that it would/should be a room temperature superconductor. The critical temperature depends on stuff that can't be probed via such simulations (i.e., electron-electron interactions).
From my understanding (I am not a superconductor person, but in an adjacent field), having flat bands at the Fermi level is not that rare. Such features appear in other materials that are evidently not superconductors, room temperature or otherwise. So the conclusions are more along the lines of "maybe it wouldn't be totally crazy", rather than "omg, we predict this material has astounding properties".
