We like to think of it as a feature :-) There are things we do well in deal.II, like all of the finite element stuff, but we decided a long time ago that we don't know enough about mesh generation and visualization (i.e., pre-processing and post-processing) that it is best if we leave this to the experts. That's particularly true given that there is such high-quality software out there for these tasks. That said, the latest deal.II release has interfaces to gmsh built in. I believe that you can now generate meshes internally, by calling gmsh under the hood.
