One way to solve this problem while ensuring type safety (or at least get rid of the need for dynamic casts) is to attach all callbacks directly to the system, which wouldn't know anything about the solver. The solver then would have a reference to NonlinearImplicitSystem and forward all PETSc callbacks to it. That, however, would be a substantial design change. In particular, the user would have to instantiate a solver with a given system and call solver.solve() instead of system.solve().
