I have a engineering-physics degree, and while I will admit my day job involves more down to earth physics software simulation rather than advanced cosmology and particle theory, I would categorize WIMPS more so as the model with the least amount of gotcha's when compared with alternative gravity theories. I for one lean towards alternative gravity theories.
"They behave similarly to neutrinos except are much more massive..." And yet we can build neutrino detectors and "see" neutrinos. So far similar detectors for dark matters have failed to detect anything:
Lack of detection, plus this sparse galaxy with no sign of dark matter, is starting to slowly rule out the simpler explanations by virtue of outliers that don't fit any model.
You yourself mentioned it, but I always remind detractors that the standard model IS WRONG.
The sparseness of this galaxy is what intrigues me. What if the lack singularity at the center is the key?

But none of the ultra-diffuse galaxies discovered so far have been found to be lacking in dark matter. So even among this unusual class of galaxy, NGC 1052-DF2 is an oddball.
