I agree that most code review change requests are style-related.
One reason I can think of this happening is that in order for one's brain to focus on just the parts of the CR that matter, stylistic oddities need to be sorted out. Ideally after some time, a reviewee would stop opening PRs that contradict the basic stylistic standards that the group adheres to (and thus stop wasting everyone's time). Ideally there would also be a linter to get everyone to that point as quickly as possible.
Imagine if you were running an assembly line, and every person in every shift did their welds significantly differently. It would be a waste of time for the inspection workers to have to continuously remind everyone that it's hard to check quality on a variety of different welding methods, rather than just one or two. It would be a better use of everyone's time to just agree on what kinds of welds are acceptable.
