Do we actually need this anymore? It seems like we should be able to just use the default excludes.

[alinabuzachis]

I tried to add the only ones non listed https://github.com/ansible-network/github_actions/blob/main/.github/workflows/unit_source.yml and https://github.com/ansible-network/github_actions/blob/main/.github/workflows/sanity.yml. Correct me if I am wrong. I will prepare a PR for the other branches too.

[gravesm]

This change won't work because changes in this repo aren't merged with the defaults, they completely overwrite. What I'm suggesting is that we just don't provide a matrix_exclude at all for the unit test workflow and just use whatever that action defaults to. I don't think we can do the same yet for sanity because of ansible 2.9.

this triggers are impacting changelog workflow only, we should create a different file for that and all_green does not need to changelog being success as this will fail automatically
anyway we can keep it like that as it is already like this in the main branch

Once this is merged, if you want, you can open a PR against main and backport to stable-6 and stable-5 this way we ensure consistency between branches.
