I'm on holiday up until end of next week so not going to go this trough
right now but I have minor complain ;-)

Please use:

       --[no-]cc-cover
           If this is set, emails found in Cc: headers in the first patch of the series (typically
           the cover letter) are added to the cc list for each email set. Default is the value of
           sendemail.ccCover configuration value; if that is unspecified, default to --no-cc-cover.
       [from "man git-send-email"]

This will make the commits less bloated and makes sure that everyone you
might want to CC will get always the same set of patches.

I'd also recommend to pick only one list for to-field because there can
be only one maintainer that in the end would take these patches. Change
rest to cc's. Now the process of managing these patches is ambiguous by
definition.

BR, Jarkko
