The spec says:

Requests with a version lower than that of the proxy/gateway's version MAY
be upgraded before being forwarded; the proxy/gateway's response to that
request MUST be in the same major version as the request.

How about the following:

1.0 Client - 1.1 Proxy - 1.1 Origin

Client sends request to proxy, proxy forms 1.1 request to origin, origin
starts CGI program, CGI program generates response sans Content-Length,
origin chunkifies entity body, origin sends
chunked/no-transform/digest/whatever response to 1.1 proxy, proxy MUST
remove the chunking before sending it to the 1.0 client.
