I agree this slightly weakens the case for change, but it's not really the same thing. Adding a "format_mapping" method allows an arbitrary mapping to be used with any keyword-based format string. Crafting a special format string in order to use an arbitrary mapping means that the same format string can no longer be used with an ordinary keyword based call - you have to do "format(m=dict(name=y, country=z))" instead. Moving the decision of "how am I going to be called" to the time of writing the format string is a bit odd. On the other hand, the specially crafted format string does have the virtue of travelling far more easily through any APIs that wrap the basic format() method (since it doesn't need special treatment to make its way through the wrapping code).
