Thanks Jeff for restating the policy.

According to the release lifecycle doc
  • Missing features from newer generation releases are back-ported on per - PMC vote basis.

We do not have a policy to prevent new features strictly for the branches in maintenance state. 

IMO, the patch qualifies as the missing feature. (As said, it is useful for Cassandra Analytics, and it is good to have the same bridge implementation amongst different cassandra versions)

Therefore, I would like to call for a vote. 

Sure

I’m -1 on 4.0 and 4.1

Everyone has a low risk change they want to backport to every branch, 4.0 and 4.1 in particular are way past the point we should be adding features

The policy exists and it’s a pure feature not a regression

The patch is low risk for Cassandra server as it only touches CQLSSTableWriter, which is only used by toolings.
