In general it is desirable that cleanup is the reverse process of setup.
In this case I am not seeing any particular issue, but with the
introduction of devlink-sb for felix, a non-obvious decision had to be
made as to where to put its cleanup method. When there's a convention in
place, that decision becomes obvious.
