Review comment:
Looking at the values of `ARROW_SIMD_LEVEL` `NONE` is correct for the
conda-forge case. We cannot build packages with `SSE4_2` by default as there
are still (supported) users without it. I've opened an issue at
https://issues.apache.org/jira/browse/ARROW-15445 With the workaround here,
we're fine for now but sadly https://issues.apache.org/jira/browse/ARROW-15444
is an issues that should block the release as especially the CUDA builds are
used by several downstream users.
