Why is he being downvoted?

As per RFC2119 (http://www.ietf.org/rfc/rfc2119.txt):

    3. SHOULD   This word, or the adjective "RECOMMENDED", mean that there
    may exist valid reasons in particular circumstances to ignore a
    particular item, but the full implications must be understood and
    carefully weighed before choosing a different course.

Because the problem goes beyond failing to invalidate the existing cache for the resource (which is a SHOULD), Chrome does not even make the request, which most definitely isn't acceptable under any circumstance, even after careful considerations. The spec even emphatically says that responses to a DELETE are not cacheable, how could you use an existing cached response as valid for a DELETE if you are not allowed to cache a delete in the first place?
