Works like a charm. I tested with:

packages:
  - git: https://github.com/fishtown-analytics/dbt-codegen   # 'master' branch default
  - git: https://github.com/tailsdotcom/dbt_artifacts        # 'main' branch default
  - git: https://gitlab.com/gitlab-data/snowflake_spend      # 'master' branch default

And:

$ dbt deps
Running with dbt=0.19.0

Thanks for this @VasiliiSurov!

@jtcohen6 , can you also test with:

packages:
  - git: https://github.com/fishtown-analytics/dbt-codegen 
    branch: master
  - git: https://github.com/tailsdotcom/dbt_artifacts   
    branch: main

I think those should give the same warning

[jtcohen6]

@clrcrl Good call! Even if the user specifies the default branch, we should raise this error. They have recourse to disable via warn-unpinned. I'll open a follow-on PR and tag you.
