 ## Branch protections
 
-The order of branch protection rules
-[can be important](https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/defining-the-mergeability-of-pull-requests/managing-a-branch-protection-rule#about-branch-protection-rules).
-The branch protection rules below should be added before the `**/**` branch protection rule
-(this may require deleting the `**/**` rule and recreating it at the end).
+### `main`, `release/*`
 
-### `main`
+- Restrict who can push to matching branches: CHECKED
 
-* Require branches to be up to date before merging: UNCHECKED
+## Code security and analysis
 
-  (PR jobs take too long, and leaving this unchecked has not been a significant problem)
-
-* Status checks that are required:
-
-  * EasyCLA
-  * required-status-check
-
-### `release/*`
-
-Same settings as above for `main`, except:
-
-* Restrict pushes that create matching branches: UNCHECKED
-
-  (So that opentelemetrybot can create release branches)
-
-### `renovate/**/**`, and `opentelemetrybot/*`
-
-* Require status checks to pass before merging: UNCHECKED
-
-  (So that renovate PRs can be rebased)
-
-* Restrict who can push to matching branches: UNCHECKED
-
-  (So that bots can create PR branches in this repository)
-
-* Allow force pushes > Everyone
-
-  (So that renovate PRs can be rebased)
-
-* Allow deletions: CHECKED
-
-  (So that bot PR branches can be deleted)
-
-### `benchmarks`
-
-- Everything UNCHECKED
-
-  (This branch is currently only used for directly pushing benchmarking results from the
-  [overhead benchmark](https://github.com/open-telemetry/opentelemetry-java/actions/workflows/benchmark.yml)
