No, I didn't imagine for a second that you had!

I think that's a doc bug.  "The plan is to ..." should read: "The plan
was
originally to ...".  (Well, at least in the 3.1 version of the
"what's new in 3.0" documentation;  the 3.0 version that you linked to
isn't even autogenerated any more, AFAIK, so fixes to the ReST source
for that file never make it to the web site.)

I'm a little confused myself about what's actually happening with
% formatting, but here's a fairly recent python-dev posting from
the BDFL:
