A major backwards compatibility break will not happen without a major
number change to Py3. And I expect it to happen -- the 'as yet' was
intentional. In fact, here is my New Year's prediction (with subjective
certainty > .5):
a. The PyPy project will succeed.
b. Python3 (actually, the reference implementation thereof) will be written
in Python3 (perhaps with 'draft' in Py2).
c. We will see it within 5 years.
We will see if I am any better than the tabloid 'psychics'.

You can certainly share your concerns with the PEP author. I believe that
there is also a PyWiki page that you can directly add to.
