Sure but then we can as well keep them -) But maybe I will first redo them in a less old school way. The reason i ask mostly relates to trying to classify such commands. It is easy to see that one should not redefine \relax (primitive) or \framed (permanent core macro) so we can protect these against overloading, while \temp is supposed to be mutable (\foo_bar are already hidden from the user to these i can skip). There are (local) cases where we have \3 defined but what should it be otherwise? And commands like \n ? Commands like \NC have a meaning that depend on the specific environment so they change meaning but then still need to be protected against overload. Most is already dealt with so i'm now going through left-overs.
