Exactly. If % formatting is removed in 3k, code breaks, so we keep it. Changing it now so that code breaks anyway is not productive :)

Just to clarify, I'm not advocating change here. My comment (above) about code breaking was in reference to an issue with a chunk of user-level code which got clipped from the quote, and is completely unrelated to any diiscussion of changing Python.
