This largely saves bandwidth when there are multiple users (not all
the users, only multiple) connected from the same proxy, or where the
fire and forget mode is used and the users on the proxy service say
something. The interesting thing, mainly, is that it saves
round-trips, which are expensive, rather than bandwidth, which can be
helped with compression.
