 Replying to [comment:3 jmroot]:
 > That issue is from early 2021 and references a report from 2020, so it
 can't possibly be specific to Ventura. Anyway, the tl;dr appears to be
 that bsdtar handles sparse files differently than gnutar.

 I disagree with you. I've found at least one example of such a binary
 package. When I use `/usr/bin/tar` from MacOS 13, I can't decompress it
 either:
