I since added this:

"""In particular,
the moratorium would include Python 3.2 (to be released 18-24 months
after 3.1) but (unless explicitly extended) allow Python 3.3 to once
again include language changes."""

My time machine doesn't work very well in the future. So I can't tell
what we'll find necessary 2 years from now. But I would be fine with
defining the time limit to be max(time(3.1) + 2 years, time(3.2)).
I.e. the moratorium (unless explicitly extended) ends as soon as 3.2
has been released *and* at least 2 years have passed since 3.1.

They haven't changed my mind.
