I'm really sorry however we had to revert this change since it brings a blocker
issue with {{ArrayElementOutputTypeStrategyTest}}
which is constantly failing even locally like
{noformat}
[ERROR] Failures:
[ERROR]

expected: "INT NOT NULL (AtomicDataType@26e4eacd)"
but was: "INT NOT NULL (AtomicDataType@1716b369)"
