I think this greatly misrepresents the general attitute of the XFS
developers.  We take sanity checks for the modern v5 on disk format
very series, and put a lot of effort into handling corrupted file
systems as good as possible, although there are of course no guaranteeѕ.

The quote that you've taken out of context is for the legacy v4 format
that has no checksums and other integrity features.
