    This convention means that all daemons for services on
    ports < 1024 need some special privilege.
    AFAIK, this was used in the past to confer some trust
    on all daemons providing these services. (The
    assumption was that if the system administrator ran
    it, then it must be trustworthy). This thinking harks
    back to an era when SysAdmins were a select breed, not
    just any punk with a linux box.
    Nowaydays it has been realised that trusting any other
    machine, even on your home network, is naive (because
    it could have been subverted).
    Explicit trust and authentication mechanisms have
    implemented instead (to a varying degree of of
    efficacy).
    Modern networks are a lot less trusting. So the extra
    risk run giving these daemons extra privilege is
    wasted, I think.
    
    Please correct me if I'm mistaken.
