It is demonstrated in systems_of_equations_ex6, though. Personally, I use it a lot in app codes. I find it to be a good way to control solver options programmatically, i.e. without relying on command line options. You can override configure_solver and basically write whatever PETSc code you want in there to set the solver options. We could certainly add SolverConfiguration implementations to libMesh, but the main point was to allow users to customize solver options themselves, so I guess no one had a need to add any specific cases to libMesh so far.
