7z only supports some ancient tar formats but not POSIX.1-2001 and it does
not behave correctly for uncompressing data as it does not implement the
compress(1) CLI. xz e.g. was written in order to get a compliant CLI for the
7z compression method.

I use it all the time on windows... posix?!?   what's that?
wait...did I SAY it handled ".Z" extensions...no.... um... like can
you read?  It doesn't wash your socks either!...
"It doesn't wash your socks either!" - that would be awesome feature...

Does bzip2 handle .Z?  does xz? You are missing the point.
I'm not suggesting it replace tar or cpio, or cab-create,  or
a linker...or any of the other formats it can read (it's great
to try on an exe files... shows you all the loadable parts, and
all the resources...looked at just like a directory of files..
I was just suggesting it was a bit more flexibile than having to
add xz/lzma/zip/gzip/bzip2...ok, so it doesn't handle .Z, but have you
ever used. .Z?
I got the source for it and tried compressing... it was slow and sucked!
it was worse than zip gzip bzip...just about anything.
gzip was far faster and better, than compress...I literally
deleted the binary off my system so I wouldn't use it accidently,
thinking that since it was so protected and patented for so long it
must have been good... Ick!
As for xz, it doesn't seem to handle the variety of files that 7z did, which
is sad..they made it conform by making it stupid.  Typical.
xz is just a plain implementation of the LZMA algorithm. It's not
meant to be a swiss army knife of packing utilities :)
...
ok, the cmdline syntax is a bit much like "zip"... so if you
can't handle that,  then you SOL, but it at least has the ability
to R/W STDIN/STDOUT, which I don't think zip provided for (maybe it
does, I just don't know about it)....
