We do have sufficient control over the git hooks.  You can set 
commit-extra-checker (in refs/meta/config:project.config) to point to a 
script that applies such checks to commits.  See 
/git/gcc.git/hooks-bin/commit_checker for example; that includes code:

    # Reject commits applied via "git am" with list email address as
    # the author.
    if author_email in ('gcc-patches@gcc.gnu.org', 'libstdc++@gcc.gnu.org',
                        'fortran@gcc.gnu.org'):
        error('When applying a patch from a mailing list, make sure '
              'to use the original name and email address of the patch '
              'author, not the list email address with "via Gcc-patches".')

These checks are only applied to commits new to the repository, not 
commits new to a particular branch but already present in the repository, 
so applying stricter checks to new commits on particular branches can be 
trickier (see <https://github.com/AdaCore/git-hooks/issues/20>), but for 
this particular issue a branch-independent check should suffice.
