I have come across several works that omitted the citation of relevant related literature, but clearly are camera-ready versions already accepted/presented at a conference or journal. Of course, due to the familiarity, these missing works may include some of my own papers, but for the sake of this argument, it should be assumed that they may also include the work of others.
What is the general expectation on discussing such omissions with authors?
Is it recommended to reach out to the authors post-publication and point out to them which resources/related literature they "missed" (IMO)?
I also want to add that I presume the omission is usually in good faith, i.e., simply because of the lesser popularity of these methods. As the answer may depend on the field as well, I am active in the area of Computer Science, which tends to have a comparatively high publication turnover.
