 ## To be added
 - Block merging if not all defined checks pass. For example: a `verified` label was added and at least 2 approvals.
 - When a PR is opened, add reviewers (requires updates to OWNERS file(s))
-- When a PR is reviewed/commented by a user who's not the PR owner, add `reviewed|commented|approved-by-<username>` label
 - When a PR is ready to be merged (all checks passed), add `ready-to-merge` label
 - If a label is missing from the repository (i.e was manually deleted), add it back (label colors should be defined as well)
 - Tests
