The plasma redshift idea would fit in here too, in that the same ionization front/shockfront/propagating double layer that would be bending the light, would also have the free electrons to contribute to the redshift of the lensed galaxies. Might this idea be tested? For example in the mainstream model, a massive object will bend all the light on that sightline, from the slightly more distant galaxy, to the most redshifted galaxies. Meaning we should see a full range of redshifts in the lensed objects. The plasma redshift idea would suggest that even a slightly more distant object (right behind the lensing object), would get a disproportionate redshift. In other words, we should see disproportionately high redshifts in the lensed objects, correct?
It’s probably a certainty that these (active) Ionization Fronts (“shells”, shocks, double layers, interfaces, boundaries etc) induce higher electron densities. I would agree that there is probably room for plasma redshift contributing to the overall redshift picture (treating electrons as a one component plasma) , probably testable via the redshift of dispersion measurements? Not sure though.
Here is a reference with regard to redshift of lensed objects relative to redshift of foreground objects.
CASTLES Survey : Column Zs= source redshift, Z
l is the lens redshift, E(B-V):
The Galactic extinction: Reddening from dust (loss of *wave* energy; not "tired" photons - there was less of the wave energy from primary source to stimulate photon production - therefore, new photons were simply re-emitted, at the boundary ,with lower energy levels, the electron did not have far to 'relax').
The problem is that temperature, pressure, recombination, ionization, gravitation, velocity, resonance, oscillations, electron dynamics, nucleation towards crystallization (staring at variable mass theories here) - all of these, and probably more, can individually induce contributions to redshift and blueshift effects - let alone when they are superimposed atop one another. There are however a multitude of works trying to statistically differentiate contributions from some of those qualities. The title alone of this next document exemplifies the nature of part these problems:
Reddened, Redshifted, or Intrinsically Red? Understanding Near-ultraviolet Colors of Type Ia Supernovae: Peter J. Brown1, Nancy J. Landez et al
I don't usually follow bb cosmology (most redshift queries on Google are saturated with it) and was not aware that there is a "
Reionization Problem"? Apparently; can't find enough UV sources to ionize the hydrogen.

Refer again to the three models portrayed in Figure 1 of the Sunburst Arc paper (as examples). Note the idea that UV emitting sources and the extended environment of shells, or boundaries, can be ionized to such extent that some regions can become porous (optically thin), or have ‘holes’ of various sizes (Lyman a Escaping), At other times the hydrogenic clound(s) can be so dense (optically thick) that the boundary absorbs most of the UV radiation. Although ionization still occurs; a path through some portion of the boundary hasn't appeared. Like the porous heliosphere of this solar system this dynamic allows stuff from the outside to “leak” in, and simultaneously stuff from the inside to “leak” out. Then have a look at this next Chandra image with these relationships in mind paying particularly close attention to the close-up (larger view at mid page) in comparison to the larger spherical shell surrounding the inner secondary ionization phase:
Abell 30: X-rays from a Reborn Planetary Nebula
Despite the usual language a more cohesive context of the overall episodic dynamic comes to into view. Abell 30 appears to be undergoing the second of two radial pulsations (discharges if preferred) separated by some period of time. Inside the inner shell closer to the central source “Filamentary Infall” of (probably magnetized) hydrogenic matter from the lager transparent surrounding cloud is "falling" (or being attracted towards) the central source.
These nebulae, shells and other inner dynamic processes are what background light sources are being refracted through. I still don't see where, how, or what, "spacetime curvature" has to do with
any of it. It seems to me that a wonderful opportunity has been missed to usher in an entirely new field simply called
'Astrophysical Optics'.
