I think we are missing it. The Hybrid not only enables EVTOL because watts/kg needed for true EV are still far off on the horizon to be viable but so much more. And that is not just the fact that turbines are omnivorous, for any new e-fuel or even gaseous fuels. The big one will be the addition of a Recuperator to increase fuel efficiency up to 30%, that what no one in this arena is discussing. It’s probably the thing they are keeping close to their chest. This is on top of all the other fuel saving technologies that can be incorporated that have been utilized off and on for years in their Turbofan brethren such as, fuel pre-heat, brush seals, oil free bearings, etc that may not have been incorporated in the APU arena.
