Because a SHOULD means it's the recommended method, and as shown in this
case it's not a good general purpose recommendation.

The optimization to have proxies reduce the traffic sent to the
requestor by eating the unwanted parts of the response when the server
responds with more data than requested should imho be a MAY, not a
SHOULD.

For a server the situation is different as it has control over the
requested resource.
