Translating existing code is a small problem when the
language changes backwards-incompatibly.  The larger
problem is unlearning what I used to know and learning a
new language.  If that happens enough, I'll stop using a
language.  One of Python's strengths is that it evolves
very slowly, and knowledge I work hard to accumulate now
remains useful for a long time.
