I might have this wrong but there was a definite use case for the semi-colon: it follows a colon in a list; can be used as a more flowing version of a bullet point list; can do so without interrupting the readers chain of thought. edit: grammarly says I'm wrong and that should be a colon followed by a comma separated list. I might just be old or confused.
