That is correct answer to a data eating bug on a stable filesystem uncovered during RC, but the correct answer is also to then perform a thorough and public soul-searching for how such a bug got introduced to the development tree from which the pull request to linus was created. Losing files for a stable filesystem is a critical bug. In an experimental filesystem, not so much, and if you're going to claim sufficient priority to break the rc convention because of the criticality of the bug, the soul-searching is going to come along with it. And in this case, the result of the soul-searching was “the combination of the technology and the community responsible for it is not ready for mainline.”
