Not only the JBIG2 fiasco was not an inherent flaw of JBIG2 itself, but any historical archive would want to use a bounded error model for any lossy compression algorithm anyway. We don't exactly know how much error is tolerable for given content, but we know that some error is definitely tolerable for most contents, and its upper bound can be used to specify the safe and reasonable compression level. Once that constraint has been met, the choice of algorithm is no longer relevant.
