Comment (by arma):

 See #24432 for an example of a situation where this optimistic data socks
 handshake patch surprisingly broke stuff.

 It's starting to look more like we're going to rip it out.

 I think it would be worth exploring whether we can do the same behavior in
 a smarter way from the browser though -- the feature essentially removes a
 round-trip across the Tor network from page loads.
