 approval once a merge request is in good shape is an important part of the review
 process, as it clearly communicates the ability to merge the change.

-### Enabling the new approvals interface
-
-Since [GitLab v12.0](https://gitlab.com/gitlab-org/gitlab/-/issues/10685), an updated approvals
-interface is available by default. In versions older than 12.0, the updated interface is not
-available unless the `approval_rules` feature flag is enabled, which can be done from
-the Rails console by instance administrators.
-
-Use these commands to start the Rails console:
-
-```shell
-# Omnibus GitLab
-gitlab-rails console
-
-# Installation from source
-cd /home/git/gitlab
-sudo -u git -H bin/rails console -e production
-```
-
-Then run `Feature.enable(:approval_rules)` to enable the updated interface.
