Hi all, I would like to propose that we drop support for manylinux2010.
CentoOS 6, on which the manylinux2010 image is based, has been EOL for over two years [1]. There is now also an official announcement by pypa that manylinux2010 support will be dropped sometime in 2022 [2] that has not received any feedback on either Github or Discourse. Since the announcement the percentage of affected users has dropped from ~7% to ~4% of Python 3.7 users [3]. ~52% of pyarrow users are on 3.7 so only ~2% of pyarrow users [4] would potentially be affected by an issue fixed by updating pip [5]. We have already had several CI issues with the manylinux2010 builds that required workarounds. There are now also issues with verification as there are no aarch64 wheels for manylinux2010 [6].
