After 15 years of python, going from client to client, my experience is the opposite: i've yet to see a code base that would not benefit from python 3. Usually people saying that just don't know much about python 3. However, I understand that those benefits might not be motivation enough to migrate in some contexts. In those cases, I advise to freeze the project in time, isolating it by vendoring dependancies and either compile it with nuitka or distribute it in docker.
