I did a pretty reasonable chunk of C++ code once years ago. I was junior level. Wanted a good review.
I got 21 comments to remove blank lines and none about the code. Thanks. Really useful. This was the team of "experts" on the code base.
Then a principle engineer reviewed some other code and oh look, actual useful comments.
Nitpicking can be worse than useless. Obfuscates or ignore real issues in the code. Seems to usually be a sypmtom of the reviewing not being competent enough to actually review the code properly.
