  We analyze recent magnetar light-curve modeling of 38 hydrogen-poor
superluminous supernovae (SLSNe), and find that the energies of the explosions
themselves, that take place before the magnetar energy is released, are more
than what the neutrino-driven explosion mechanism can supply for about half of
the systems. These SLSNe must have been exploded by a different process than
the delayed neutrino mechanism, most likely the jet feedback mechanism (JFM).
The conclusion for magnetar modeling of SLSNe is that jets launched at magnetar
birth cannot be ignored, not at the explosion itself and not later when mass
fall-back might occur. More generally, the present analysis strengthens the
call for a paradigm shift from neutrino-driven to jet-driven explosion models
of all core collapse supernovae.
