If we respond to a HEAD request with a body, we ignore all writes. However, we must still include all implicit headers.

Fixes a regressions introduced in
#47732.

LGTM but I would prefer that if kRejectNonStandardBodyWrites is true we throw before sending headers as that can give a falls sense of success. While if kRejectNonStandardBodyWrites false we have the previous behaviour where we ignore the body but send the headers.

mcollina · 2023-05-26T12:04:24Z

I do not have time for further changes to this PR and we should fix the breaking change.

Do you prefer a revert of the original PR?
