174 Optimistic Data for Tor: Server Side 181 Optimistic Data for Tor: Client Side

 This one is a performance hack that hasn't seen its full impact
 yet.  Starting with Tor 0.2.3.x, clients MAY send data to the
 exit node before finding out whether the exit has been able to
 successfully connect to the destination server.  Previously, it
 took an extra round trip for clients to wait to see whether the
 exit said "Yes, I'm connected" before they were allowed to send
 data for the exit.

 This should make connection startup faster in many protocols
 where the client speaks first (http, https), as more and more
 client programs gain support for it.

Is optimistically sending data for non-testing purposes recommended?

The "Security implications" in 181 seem to imply that it isn't, but the man page doesn't mention any risks. Is that because they are considered obvious, or simply an oversight?
