If I understand the feature correctly, it allows extensions to be just CREATEd without having them to be added to shared_preload_libraries, i.e. saving the organization an instance restart/downtime. That seems important enough for end-users to know, even if they will need to wait for extension authors to catch up to this (but I guess a lot will). Michael
