Another potential source of this information is the existing commits.  If
you are communicating with the same set of people already, you already
have the information in your repository.  I suspect Michael's "selected
few co-workers that would comfortably fit in a small list of config
entries without need for any external text file" use case would be better
served by an approach to look into existing commits.

I often use "git who Jeff" alias to fill the recipient of my e-mails with
this alias:

    [alias]
        who = "!sh -c 'git log -1 --pretty=\"format:%an <%ae>\" --author=\"$1\"' -"
        one = "!sh -c 'git show -s --pretty=\"format:%h (%s, %ai\" \"$@\" | sed -e \"s/ [012][0-9]:[0-5][0-9]:[0-5][0-9] [-+][0-9][0-9][0-9][0-9]$/)/\"' -"
