I think whether the client uses `Expect: 100-continue` is a decision
similar to deciding whether the client uses, say, a Transfer-Encoding.
The client may also be specifically configured to use a different
version of the protocol, like IE is configured to talk HTTP/1.0 to
proxy servers by default. Besides, the client may not even handle the
100-continue response properly.
