I think you misunderstood what I wrote. Suppose you decided that the API for the threading modules needs significant rework, changes which will break much, if not all current usage. I'm only suggesting that if you decide the API change is worthwhile that you take the opportunity to make the class, method and data names PEP8-compliant. I'm not talking about gratuitous change to the identifier names, but situations where the user is going to have to rework their code anyway.
