Nothing by me, but do, go back over Roy's original response.

Note that we can proxy a 1.0 server for a 1.1 client, and that client is
welcome to pass us CL chunked, we'll do the homework.

This has not changed.  If the body is smaller than the readahead buffer,
we will send it with C-L, however if the body is larger, it prefers to
be sent on in the original chunked format, unless the user configures to
explicitly use sendcl.  There's no significant increase in resource
consumption, AFAICT.

Does that make more sense?
