I like the second one better. In programming, it’s useful to have namespaces for overall organization and conflict resolution. But it’s a trade off: you are nudged into a hierarchical ontology, with all the implied issues. Wikipedia titles are free text (more or less). So they can afford not to introduce hierarchical naming and still have nice, easily addressable names without conflicts. This avoids all sorts of problems. Most things simply can’t be categorized in a strict, hierarchical manner.
