Many questions posted on this Forum are not susceptible to simple answers.
For instance, one of the more frequent questions posted is along the lines of, "What transformer should I buy for my (pick size) layout ? " Unfortunately, that depends on a variety of factors that typically preclude a simple answer.
In addition, many questions assume that there is only one way of doing things, such as,"What brand of suitcase connector should I get for my bus wire ? " The poster may not realize that there are other options out there besides using suitcase connectors that may better fit his or her needs and so the answer could reasonably explain those options/alternatives to the poster.
Although there may be times when the answers to a question go on ad nauseum, IMHO we should err on the side of providing too much, rather than too little, information.
Sorry for the long response.
