It's not listed because I think that it shouldn't exist (anybody who thinks it should is invited to write the documentation) and would like to see it disappear. In a well-organized code, one would perform a non-scf calculation with a dense k-point grid as usual; then the phonon code should take care of reading the electron eigenvalues only from the output data file of the dense-grid calculation. There is no need to have a specific option and a specific file just for that.
