I guess this stems from the fact that Python dictionaries are C creatures and they are themselves used for internal housekeeping, so no high-level modifications can be allowed to disturb language internals. This all makes sense. It is sad not to have the possibility to extend built-ins but on the other hand it guarantees a constant (predictable) behaviour, which I agree is something we should protect.
