I Gravitational self-interaction: another attempt to replace Dark Matter

From the abstract:

... Our derivation uses both EE and the Newtonian approximation of EE in Part I, to describe semi-classically in Part II the advection of DM, created at the level of the universe, into galaxies and clusters thereof. This advection happens proportional with their own classically generated gravitational field g, due to self-interaction of the gravitational field. It is based on the universal formula ρD =λgg′2 for the densityρ D of DM advected into medium and lower scale structures of the observable universe, where λ is a universal constant fixed by the Tully–Fisher relations. ...

What do you think about that or how would you characterize the seriosity of this "derivation"? It seems different to Alexandre Deur's approach.

Having not read this paper I offer no opinion on its physics content. But with regard to its "seriosity" I will just point out that, according to Google Scholar, the paper has garnered no citations in the two years since it was published.

Ok, thanks. So one could conclude that the physical content isn't very convincing. Or people don't read it at all because field self-interaction in general is judged as being a negligible effect.

It is. On an initial read this paper looks like nothing more than handwaving.

field self-interaction in general is judged as being a negligible effect.

That's the general opinion that Deur's work was trying to undermine.

However, this paper doesn't appear to me, on an initial read, to be based on anything like the kind of field self-interaction that Deur's work is based on. As above, it just appears to me to be handwaving.
