Another significant double slit experiment?

This is interesting.  The headline sums it up:

Neutrons In The Double-Slit Experiment Really Do Individually Take Both Paths

Here's another article explaining it, at Science Daily. 

And this is from the "discussion" section of the paper itself:

It should be emphasized that all results are completely
consistent with standard quantum theory. The conclusion that
particles can be physically delocalized between paths in which
no strong interactions occur and that the localization or delo-
calization is decided by a measurement that takes place after
the particles have propagated along the paths is a possibility
inherent in the paradoxical aspects of quantum superpositions.
In the present paper, we demonstrated that standard quantum
theory predicts precise and specific effects of the presence of
a particle in a path, even when the particle only undergoes a
very weak interaction on its way though the interferometer.

Now, this reminds me: back in 2017 I spotted on arXiv a Chinese paper that I thought sounded significant, regarding the paths of photons in a double slit experiment.   (It was pretty memorable for the inclusion of a very Chinese dragon illustration!)  Yet, I don't think anyone - like, no pop science site or Youtubing physicist - ever commented on it.

But now that I re-read it - I think it was basically arguing the same thing as this neutron experiment.

Maybe I should drop a line to Sabine Hossenfelder and ask her to discuss both experiments!
