Have a look at the rationale here (and the followup discussion):

 http://docs.freebsd.org/cgi/mid.cgi?4177C8AD.6060706

And also note that T/TCP was removed only from FreeBSD 6-current.  It is
still in 4.x and 5.x releases and will not be removed from them.

A more secure and much less (code-) intrusive replacement for T/TCP is
in the works by me.  I'll have code ready soon and it'll be in FreeBSD
6-current probably before christmas along with a proper RFC draft submitted
to the IETF TCPM WG.
