I once wrote a hook script for a company I work for that would send patch series e-mail when someone pushed a new tag into a shared repository, so I could comment on the changes just by replying to emailed patches. Cover letter was created from a message attached to a tag. So if someone wanted a review of some changes all that was necessary was to push their current status to a tag, which is a single command in git. No git-send-mail setup needed. It was quite nice middle ground, and didn't require me to use github/gitlab GUI. Being able to stay in neomutt for most communications was nice.
