As to the generalized Kohn-Sham scheme, the term 'Kohn-Sham' seems to be misused in this case. Indeed, out of desire to get electron affinities as the energies of virtual orbitals, the original Kohn-Sham theory is forcefully "crashed" in some (out of infinitely many) variants of the generalized Kohn-Sham "landscape" by mixing different theories both globally and with rangeseparation techniques.
