The Panopticon/Over-categorization?

I've noticed this over the past few months, but is there a reason more categories are being created? It seemed like the old categories of "other realities" or "time travel" were just fine, but now there are categories for "nowhere," "never," "nothing," "problems with time," and so on. "Theories and concepts" has become "concepts." There also seems to be circular cataloging, which I thought the wiki tried to avoid years ago, where a page will fall into several categories and then those categories are placed inside each other, kinda. I'm just wondering why this is, cause the old categories worked just fine. I understand the need for specificity, but it just seems odd. Does anyone know?
