Sure, there are other formats, but the point was that Poppler shows how document support can be provided in a way suitable for viewers using different UI technologies.
I would assume that, for example for PostScript, both Evince and Okular are also using the same library, most likely Ghostscript.
Supported formats and respective library usage will depend on the application's target scope.
A program intended to be just a PDF viewer would only need Poppler, e.g. for avoiding any unnecessary or maybe even unwanted dependencies.
Anyway, it was just an illustration how application developers using quite different technology stacks are collaborating on common code.
