I agree with a lot of the post.

Shameless plug, I suggest a workflow very similar with my own github action, https://github.com/rubenfiszel/autochangelog-action. The suggested workflow is to:

  - trigger the action through CURL
  - the action generates a changelog diff and some 
    manifest file diff with the version change (such as package.json). 
    The next version is inferred using semantic versioning and 
    conventionnal commits, respecting fix, feat and breaks. 
    With that new content, you generate a PR. 
    That PR is labeled with "autorelease"
  - When that PR is merged, another action is triggered wich do the 
    Github Release and fill the body with the changelog diff
