The report just says not to divert funding from other projects to SAF, that's pretty reasonable and expected really - At some point it might change but at the moment there are better things to spend the money snd resources on.

When the grid is green snd there is no shortage of demand even with electric cars, boats, and heating factored in then hopefully saf will have matured enough to help complete the final transition from fossil fuel or even better electric planes will take over.

Regardless the big powers will continue to research the chemistry and engineering side of SAF because it's important for space based infrastructure, no fossils in space to power the return trip.
