(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.
here's all of the events that github actions supports
