No, it's still fully supported. Every now and then someone suggests
that it's worse than .format() for some reason or another, but the
fact is that it's not going away. Use whichever one makes the most
sense.

Yes, this is a slight violation of "one obvious way to do it". But
it's handy to have both format methods; they have overlapping but
distinct feature sets.
