If you need semicolon delimiters, can't you just pass ``delimiter=';'`` to the reader or writer? I don't think there's a need for a separate dialect class for that, since dialect classes should only provide a baseline for the most broad use cases. Users have plenty of options for extending or customizing behavior without adding more dialect classes.

I also think the docs around dialects are confusing. I remember being confused by them when I was learning! I made quite a few changes to try to add clarity around dialects to the documentation. Let me know if anybody has feedback!
