That's why PR should be small. It's much better to have multiple PRs than a single big one.
Totally fair to have gigantic PR full of boilerplate code, but generally you can split the boilerplate and your feature in 2 PRs, where only the feature will get a proper review.
All of this obviously depends on the criticality of the system :p
That can lead to another problem though, which is that if a developer knows a merge is only part of the whole change, it becomes easy to assume any issues will be handled elsewhere.
yeah, fair point. it really only works with standard boilerplate code which is simple enough to not have any issue I guess.. in my case working with a NX monorepo, that would be any code created using the generators
