I would prefer merging this, so that we can merge dependent PRs (such as stackabletech/hdfs-operator#571 and stackabletech/druid-operator#584).
Yes, we are loosing some doc comment changes as well, but I would simply cherry-pick the reverted commit once we are ready for 1.80 and the changes should be back :)

Once this is merged we can IMHO release 0.73.0 :)
