Well, it seems that everyone took the opportunity to show how you can't have
all the redshifts be perfectly quantized for all observers.  But that's not
what was being claimed!  What they said is that there are peaks in the power
spectrum.

You can do this so that the effect appears to all observers.  The simplest
example is to put all the galaxies at the points of a lattice.  Then everyone
will see frequency peaks.  I don't even need the fact that observers are
likely to be near the lattice points, which increases the effect a bit.  What
Benjamin Weiner's argument shows is that if your lattice has spacing 1/f, you
will also get frequency peaks at f/sqrt(2) and so on.

Clearly having galaxies at lattice points is incredible.  A better model is
the following.  Take some sand with a reasonably uniform grain size, and dump
it into a bucket.  Measure the distances between grains, and then run the
power spectrum.  You will still get frequency peaks.

Having said that, i think the claimed peaks probably don't exist.
