TBH, I was grepping through the code and found various occasions
where IO::Compress::Adapter::Xz or IO::Uncompress::Adapter::UnXz and
IO::Compress::Xz or IO::Uncompress::UnXz are mentioned :)
lib/IO/Uncompress/AnyUncompress.pm (from libio-compress-perl in git,
2.204-1) has
41 eval ' use IO::Uncompress::Adapter::UnXz 2.204 ;';
53 eval ' use IO::Uncompress::UnXz 2.204 ;';
140 if (defined $IO::Uncompress::UnXz::VERSION and
145 my ($obj, $errstr, $errno) =
146 IO::Uncompress::Adapter::UnXz::mkUncompObject();
The only thing which comes close to some documentation is
1060 =head1 SEE ALSO
1061
1062 L<Compress::Zlib>, L<IO::Compress::Gzip>, L<IO::Uncompress::Gunzip>,
L<IO::Compress::Deflate>, L<IO::Uncompress::Inflate>,
L<IO::Compress::RawDeflate>, L<IO::Uncompress::RawInflate>,
L<IO::Compress::Bzip2>, L<IO::Uncompress::Bunzip2>, L<IO::Compress::Lzma>,
L<IO::Uncompress::UnLzma>, L<IO::Compress::Xz>, L<IO::Uncompress::UnXz>,
L<IO::Compress::Lzip>, L<IO::Uncompress::UnLzip>, L<IO::Compress::Lzop>,
L<IO::Uncompress::UnLzop>, L<IO::Compress::Lzf>, L<IO::Uncompress::UnLzf>,
L<IO::Compress::Zstd>, L<IO::Uncompress::UnZstd>, L<IO::Uncompress::AnyInflate>
Some other grep results:
lib/IO/Compress/Zip.pm:To write Xz content, the module C<IO::Uncompress::UnXz>
must
lib/IO/Uncompress/Unzip.pm: eval{ require IO::Uncompress::Adapter::UnXz ;
lib/IO/Uncompress/Unzip.pm: IO::Uncompress::Adapter::UnXz->import() } ;
lib/IO/Uncompress/Unzip.pm: if ! defined
$IO::Uncompress::Adapter::UnXz::VERSION ;
lib/IO/Uncompress/Unzip.pm: my $obj =
IO::Uncompress::Adapter::UnXz::mkUncompObject();
lib/IO/Uncompress/Unzip.pm:To read Xz content, the module
C<IO::Uncompress::UnXz> must
So lib/IO/Compress/Zip.pm and lib/IO/Uncompress/Unzip.pm mention that
IO::Uncompress::UnXz
is required (and the former should probably mention IO::Compress::Xz)

Yay \o/
