That's not true though. It says in its abstract that it can fit the Type Ia supernovae Pantheon+ data as accurately as the ΛCDM model, and also fit the angular size of cosmic dawn galaxies observed by the JWST. It is the data produced by the JWST that has led to this model.
The article goes on to say:
> The galaxies observed in the early Universe, some less than 500 million years after the Big Bang, appear to have shapes, structures, and masses similar to those in existence for billions of years
