I'm just a layman, but in this[1] paper from 2023 Deur and his collaborators took his model[2] and applied it to the Hubble Tension problem. This paper does mention fitting the CMB well (as I understand it), and the model having no Hubble Tension.

I know his work has been contentious in the past, and that his past work has used multiple models that are not entirely compatible for different problems, weakening his claims.

That said, at least from my armchair it seems like a worthwhile direction to pursue.
