portage-utils-0.73 finally can deal with .tbz2 files which are compressed with BINPKG_COMPRESS=xz and some other variants. However, BINPKG_COMPRESS=zstd and some other compressors are not yet supported. I wrote a patch which supports all compression programs which are also supported by portage. The patch is now a pull request on github: https://github.com/gentoo/portage-utils/pull/4 Let me know if you prefer some other form.
