FWIW, I raised this on the #xfs irc channel. One ask they had was:

│15:56:40  dchinner | andres: can you get a metadump of a filesystem that is displaying these symptoms for us to
analyse?
│15:57:54  dchinner | metadumps don't contain data, and metadata is obfuscated so no filenames or attributes are
exposed,either.
