(these are only my ideas)

By considering how powerful GitHub actions are maybe we could automate some tasks like merging community contributions.

Here's how it can be done :-

Step 1

In the PR template we can check to make sure that the issue is about CC.
We could test if the contributor checked the [x] is it a community contribution field in the description.

We could also add labels.

Step 2

We can see if the PR passes all other checks with GithubChecksAPI, then we will merge the PR.

After that, automatically appreciate the contributor for his/her contribution.

Step 3

If any of the checks fails then we will ask for manual review.
