I've seen good/great people call out the nitpicks (in my case it was often mis-spelling, due to not being a native speaker of english) but will approve the PR anyway (implicitly expecting another revision to be sent, trusting the submitter).
On the other hand bad/toxic people will drown you with stylistic nitpicks and won't approve (and trust) you to do your best work. You will be essentially blocked pending their approval (so that nitpicks are changed according to their likings).
The weird thing is that all this traceability leaves traces for management to see who's doing a good pr review job and who's not... But I've learned that management usually does not care much.
