Well, yes, "until Python 2.8 comes out" was meant to be a synonym for
"never". But Chris Angelico since pointed out that it would be a problem
for Python 3 since it's intended to be used for 2/3 compatible scripts.

I think I'd originally read the use case as "make Python 2 as similar to
Python 3 as possible so that people learning on Python 2 won't learn as
many bad habits", without anything about explicitly running the same
scripts on Python 3.
