There are remote replication scenarios over a WAN (mainly aimed at
disaster recovery) that want to keep a fairly updated database without
putting too much traffic over the link. People in that category really
want zeroed tail+compressed archives, but probably not the extra overhead
that comes with shipping smaller packets in a real-time implementation.
