Canonical doesn't employ any ext4 engineers, and as far as I know, no Ubuntu developers contribute to ext4 development. So the fact the release notes might get a few things wrong shouldn't be surprising. Canonical simply doesn't have any file system developers on staff, as far as I know.
If you are willing to try out Metadata checksumming, testers who report bugs are always appreciated. The way to get a feature out sooner is to get more people to contribute to those features. If you are ranting about the lack of a feature, I wonder how much more you would rant if the feature was released before it was ready and your data got damanged or lost?
