Agreed. My experience has been that the Lightroom correction for LaCA is very effective. Adobe got that feature right.
As for the example images...
I spent some time looking at #1 and while there is slight LaCA, it is exacerbated by overall softness. Whether that is caused by missed focus, air quality, or something in post-processing (noise reduction?) is not clear.
For #2 and #3, the LaCA is obvious, but I would be hard put to place the blame on the primary lens. I would like to see the same scene without the auxiliary optic. Again, Lightroom would probably clean up both with a general increase in contrast/sharpness overall.
