The removal of the [HACKERS] (etc) header will be frustrating for me: I do not sort mailing lists into folders (I simply scan the "Forums" autofilter in gmail) and have no wish to do so, and there is no way to make such a machine-readable header visible in gmail.
Perhaps those users who wish to use DKIM on their email to the list could be persuaded to remove the Subject line from list of optional fields to be signed for list email?
It seems to me unreasonable that those users who don't want to use a feature should be inconvenienced by those who do.
