+ dev, -user. We will be removing Python 2 and Python 3.5 support before the next release cut, and will start cleaning the codebase from Python 2 and Python 3.5 artifacts.
We can reference BEAM-7372 <https://issues.apache.org/jira/browse/BEAM-7372> and BEAM-9372 <https://issues.apache.org/jira/browse/BEAM-9372> in clean up PRs. Because current in-progress release (2.24.0) still has Python 2 support, I would like to defer starting the cleanup until we have approved an RC for the following reasons: - Jenkins suites that we run on the release branch are defined on master branch. - There is a possibility that some fixes not yet merged to master may need to be cherry-picked into 2.24.0. Let's make sure such changes are still Py2 compatible.
