. Just saying "ok, switch your format strings from % to {}" didn't work in Python 3.0 for various good reasons, and I can't imagine it will work in Python 4.0 unless we have a transition plan.
Do the users get any say in this? I imagine that some people are heavily invested in %-formatting. Because there has been limited uptake on {}-formatting (afaict), we still have limited experience with knowing that it is actually better, less error-prone, easier to learn/rember, etc. Outside a handful of people on this list, I have yet to see anyone adopt it as the preferred syntax.
