  In what way is bzip2 more of a "standard" than zstd? bzip2 doesn't even seem to have any official reference description of its file format; just an "unofficial" one[1], whereas zstd is RFC 8478[2]. When I evaluated various compression algorithms a few years ago zstd came ahead of bzip2 in every metric.

    That is interesting. The author of lzip has harsh criticism of xz, and admiration of bzip2 for error detection/correction and "rightsizing" the container format. I use lzip in preference to xz unless I need portability. https://www.nongnu.org/lzip/xz_inadequate.html https://www.nongnu.org/lzip/xz_inadequate.html

      As far as I know xz and zstd and completely unrelated?
