This is an excellent idea. However I would use ALLOCATED_TO_LIR and ASSIGNED_TO_END_USER. That way we clarify the subtle difference while maintaining consistency with existing documentation.

(If I remember correctly the term DELEGATED was suggested at the time, but not used because of its usage in the DNS context as well as the connotation of total transfer of authority over the resource which is not quite the case.)

To me "DELEGATED-TO-LIR" makes sense, as it infers that the process of further delegation can be used with sub-blocks and/or atomic units can be "ASSIGNED-TO-END-USERs with the inference that no further sub assignments are anticipated. Geoff
