I write papers too and hate finding a new way to say "my X is a Y that does Z". Especially if it is your tenth paper on the topic and you should even sound like the previous nine times. But about three sentences into the introduction (where you explain all the background) you start going into "there is also Y's that do Z backwards". Which Y's you compare and connect with is important and says alot about how you think about your X. It might even be a new way of looking at it. So telling other people how you think of it can be important. And another 5 sentences in you start referencing previous work on the topic. At this point you are crediting other and you get to chose whom to credit how much, with the benefit of hindsight. You refer to papers that are useful to people new in the study of capital letters. What you write here helps them much more than a mere list of papers or a google (well google scholar or ADS or pubmed or what ever) result list, because you can provide a good order to read them or which aspect of X's are best explained where. You also name papers that might be useful to practitioners in the field because they have a particular technique or a good explanation of it. So it is very much worth while of providing the background that others expect at the beginning of your paper. Even if it requires rewriting that first paragraph several times.
