Comment 2 for bug 1295153

Considering the maintenance burden there would be maintaining two Python3 versions during the 5 year 14.04 support lifetime, I think this is a great idea. Even if there are a few Python 3.4 related rough-edges in some packages that might need SRUs early in 14.04's life, it still seems to me like removing Python 3.3 means a lot less work for you folks overall.

That's just my two cents as someone who uses Python3 heavily in production :)
