I'm not saying there aren't other issues - there certainly are. What you highlighted is one of them. All I'm saying is that The Grand "Me-vs-You" peer review process is gone.
Anecdotally, I can say with confidence that some teams have a lot of autonomy in deciding to follow (or not follow) company-wide practices / guidance like what you've posted (obviously, only a few do it, since non-compliance isn't officially blessed). I was lucky enough to work in a team which was much better than baseline. But I try not to let that colour my memory - I heard and saw plenty of horror stories, and I saw plenty of people (including in my leadership) trying to do the right thing. Like most things, there are shades of grey here.
