I don't think this can be counted as ack - neither do I recall having seen this
ack on the list, nor did you Cc Eddie (I specifically did not alter the Cc list
here), i.e. he would also have no way to communicate his objection to this.
Please be transparent here (and I think I told you to Cc maintainers on your
patches enough times by now).
