I have a policy in my team that if they find something that isn't compatible with python 3 then they should make it compatible and release it back. For now, this has come up with some creative workarounds as they're a little nervous of community contributions!
I've seen similar things done with my projects as well. There are fewer and fewer good reasons to write Python 3 incompatible code. Most, if not all, of the large popular libraries have support for it.
A huge benefit to your team's approach is that it forces the developers to be aware of python3 incompatibilities and to learn new concepts.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
