Actually, there are legitimate uses for this sort of API.  The patch 
allows an administrator to kill specific connections that are in use by 
other applications, where the close is not available, since the socket 
is owned by another process.

Anything that wants to act as an external agent to manipulate
or terminate connections should use netfilter.
