 Replying to [comment:1 Tim Graham]:
 > It's not clear to me what you're proposing. If I understand the scenario
 you're describing, you'll get an error if you run `makemigrations
 --check`. Is that insufficient?
 > {{{
 > $ python manage.py makemigrations --check
 > CommandError: Conflicting migrations detected; multiple leaf nodes in
 the migration graph: (0002_auto_201808429_2051, 0002_auto_20180829_2051 in
 polls).
 > To fix them run 'python manage.py makemigrations --merge'
 > }}}

 That is probably actually bang on. Cheers! Perhaps I should have read the
