We didn't deal very well with names that didn't have pre-defined NIDs, as the NID zero travelled through the full process and resulted in an inaccessible method. By consequence, we need to refactor the method construction callbacks to rely more on algorithm names. We must, however, still store the legacy NID with the method, for the sake of other code that depend on it (for example, CMS).
