This. Without a systematic way to detect and convert %-style to
{}-style formatting, enforcing the switch in the 3.x series just isn't
practical. Heck, we still haven't figured out how to convert a lot of
higher level APIs to the new scheme in a backwards compatible way
(that's why modules like logging still default to %-style, with
{}-style only available via options and wrapper objects).
Cheers,
Nick.
