Since you seem to be interested in migrating your application code in order to take advantage of Python 3, my advice is to (ta-da!) start migrating your code. And when that's done, stop looking back.
I'm sure he's thinking that way for himself. To be fair, though, as he describes it, Ian is evidently not the boss in the commercial projects he's talking about projects. He needs to convince others that Python 3 is a practical solution to their problems.
This makes the idea of lobbying for Python a real enthusiasm drainer. I'm still all for it, but we should recognize the social aspects as well as the technical issues.
Unfortunately, I'm not sure what, if anything, we can do to help support developers like Ian who can't impose Python 3 -- but rather has to expend personal energy and reputation in lobbying.
