comment Double slit with opposite circular polarizers
I think you have a point that quantum effects are fragile and it's possible that quarter wave plates "break" some of the photons making them unable to go through both slits and giving interference pattern but at least some of them must must be able to go through quarter wave plates "unobserved" since in the experiment I cited interference pattern can be seen in some cases.

comment Double slit with opposite circular polarizers
Thank you. That's exactly what I thought. So the only way to get interference pattern out of this setup would be to shine linearly polarized light but with 45 deg orientation so that quarter wave plates either slow down whole of it or none of it and won't create opposite circular polarization. Is that correct?

Besides ... I'm not asking about any quantum effects. You could consider this setup classically with light as continuous wave.

I don't think that's true. If that was true this quantum eraser experiment could never show interference pattern because what I described is the part of this apparatus: en.wikipedia.org/wiki/Quantum_eraser_experiment

Ok. But it would result only in redshift (no blueshift) if all the galaxies were moving away from all other (and ours). Is that impossible in nonexpanding space?

comment Isn't wave particle duality of light actually cheating?
I prefer to think that particles and their movement are not real and detectors just observe interactions between waves of object and waves of detector that reshape and narrow down the waves and exchange energy but we like to think there are small things bounce of each other because math of evolving narrow waves is very similar to that of a pool table.
