Ugh, yes! My own discipline most commonly uses citation styles that require a page number (if there is one) for in-text citations, fortunately.
It drives me absolutely bonkers when I read something in another citation style that doesn’t require it. What if I want to check the passage the author’s referring to in order to improve my understanding of the argument they’re making?
The page number(s) help me follow — and, if I’m writing something myself, participate in — the larger conversation. Which is precisely what I try to teach my students citation is for. It’s not only for giving appropriate credit to others for their ideas, important as that is.
