<pre>Steps to reproduce:
On macOS 10.12, download the release .tar.xz file and try to open it from
Finder. Amazingly, the Mac "Archiver" tool runs and *compresses* the release to
a .tar.xz.cpio file.
As it happens, the Mac OS "tar" utility will automatically uncompress .xz
compression when extracting (whether you ask it to or not)... but even this is
an undocumented feature of the tar program.
Could/should we ship a file format that the tools installed by default on the
system are able to handle properly? .tar.gz files appear to be handled properly
by default.</pre>
