  I think in the checklist after `bumpversion` we can add:
  
  ```
  git push <remote> <branch> --follow-tags
  ```
  
  which according to this [SO answer](https://stackoverflow.com/a/26438076/2337392) is the "sane" way to push tags as it
  ```
  It pushes both commits and only tags that are both:
  
      - annotated
      - reachable (an ancestor) from the pushed commits
  ```
  
  I don't completely understand the differences between annotated and unannotated flags, but I tested our `bumpversion` tags, and they qualify.
