It's only a problem if you are relying in it to detect and correct errors. I've got SHA checksums and FEC and ZFS and cascading backups for that, which are deliberately not relying on one code provider not having critical bugs. Also, I may have crypto, and I need error detection and FEC on the outside of that. So it seems like a storm in a teacup really. I think there is scope in xz to embed some FEC in the archive as a backwards compatible extension. Not such if the decoding scheme could be changed to reduce error cascades etc.
