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).
