One thing which seems obvious now is that since format() delegates to

find anything about the formatting syntax supported by
float.__format__. Where might I find it documented that "{:.3}" is
synonymous with "%.3g"?
You won't, at least not that I'm aware of. I think part of the problem
is that there was a lot of confusion as to whether or not the old style
formatting was to be deprecated. See http://bugs.python.org/issue14123
which refers to http://www.gossamer-threads.com/lists/python/dev/969817
