Hey @pwntester, thanks for this! I added some more CSV rows for the fluent methods of StringJoiner, tests, and a change note.

Thanks @Marcono1234, those are good suggestions. I had doubts about setEmptyValue and that's why I didn't add it in the first place, but even if taint would only get propagated in certain cases (when no other strings are joined) I guess it makes sense to have the model.
