I don't disagree with the general sentiment than one have to 
evolve the codebase along with the tooling, but if C, C++, Python 
and JavaScript didn't provide backwards compatibility in their 
maintained "production lines" then I most likely wouldn't use 
them and switch to something more stable...

So, I have no problem with Python going to Pyton3.x, as long as 
they update and maintain Python 2.7...
