Is there another type of error, that is being obtained from PDE's that I am overlooking? I understand, it resolves the time dependent features one is looking for. So, for the sake of the question, if one does not care to resolve the time dependent features, why would one need proper CFL condition for solver stability in an Implicit Method.
