When a PR is evaluated as critical (like for CONTRIBUTING or major feature), we need to have a review and a validation from all members of @EngineSquared/coreteam. Currently, we don't have any way to verify that and block CI if reviews are not made.
Add a tag that indicate that a PR needs review from all @EngineSquared/coreteam, create a CI job that fails if all reviews are not made and add this process into CONTRIBUTING.
