is udp port 1434 now useless?

[Steve Bellovin <smb@research.att.com>]

In order to stop the spread of SQL.Slammer, many ISPs and end-users 
installed filters to block all traffic to UDP port 1434.  I wonder if 
those will ever go away.  We still see Code Red attacks; I wonder if 
this will die off faster.  When will people remove their filters?  If 
they don't, random UDP-based apps are going to fail at random times 
when they just happen to bind to local port 1434.  That might be a very
strange failure mode indeed.
