Right. And I'm not even convinced that we really know the extent of the
bug; it seems fairly plausible that there's further incidences of this.
There's also the issue that the mechanics in the older backbranches are
different again, because of SnapshotNow.

That we're scheduling a bugfix for the next point release.  I don't
think we can truthfully claim that there's no known corruption bugs in
any of the  release in the last few years.
