My personal preference is to delete the branch name after I’m done with a topic branch.
Instead of trying to use the branch name to explain the meaning of the branch, I start the subject line of the commit message in the first commit on that branch with “Branch:” and include further explanations in the body of the message if the subject does not give me enough space.
The branch name in my use is purely a handle for referring to a topic branch while working on it. Once work on the topic branch has concluded, I get rid of the branch name, sometimes tagging the commit for later reference.
That makes the output of git branch more useful as well: it only lists long-lived branches and active topic branches, not all branches ever.
