Indeed, the names of the applications are imlementation details. For example, we don't expose Okular at all in the interface. When you launch Books, which is just Files listing files that match our concept of "book" (epub, pdf, etc), and then open one of the documents, the touch version of Okular opens .. but the person in front of the tablet will just see that they've found and opened that novel by Orwell they've been meaning to get to (or whatever).
This is true for most of the applications shipped as part of Plasma Active, because as you noted, those names just aren't critical to the use experience.
I know you were probably be facetious, but .. well .. you were right all the same ;)
