Deleting a Feature Branch

Section 4.6 Deleting a Feature Branch

Once your changes have been merged into the upstream main, and you have synchronized, there is no need for you to retain your feature branch. There is no harm in keeping it. But most developers will delete them to avoid having their repos become cluttered with old feature branches.
