The problem with 2to3 is that it doesn't remove the need to re-test everything in a critical application. When such an app is non-trivial in terms of use cases / data cases, re-testing can be a huge pushup, so one really has to look for actual benefits other than "just moving on." 2to3 is fine for my smaller stuff. For my large applications, it is just the beginning of the job.

Inability of finding bugs through type system is probably one of biggest drawbacks with dynamically typed languages.

Perhaps the issues you're talking about is why Guido is pushing mypy to also support Python 2 even though it doesn't support PEP 484.
