While I obviously agree with this statement, I don't think it brings
much information to other people reading the commit message. Even
though the cover letter has more information, it won't be immediately
available to people reading the patch. Also the cover letter will be
lost if the patch gets picked up for the -stable trees.

Appart from that, I'm fine with the patch of course.
