bsdtar is preferred over 7-Zip by some Linux distributions due to arbitrary code execution vulnarablities in 7-Zip like CVE-2026-48095. libarchive's xar code was unfortunately buggy (fixed betwee 3.7.2 and 3.8.5) so keep 7-Zip as fallback. bsdtar from macOS' Command-line tools is at least in macOS 15 buggy as well.
