There are persons here that mentioned they wish to wait for 8.2 than agree with 2/3 on the feature where the syntax might not be the most forward compatible one. One alternative could be to agree on a voting scheme where there could be 3 options: - No. - Yes, but only with (X&Y)|null. - Yes, any syntax, with additional vote on preferred syntax aiming for 2/3 on the second or third option.
