I tested the free tools (on Ubuntu 16.06) which generated and extracted
rar abd 7z files. I did not test their compatibility with the latest
version on windows.
Bsdtar indeed openes these formats as well, but as far as I can see,
does not generate these formats.
So it seems, that given the difficulties concerning technical and
copyright issues, that these formats should not be added officially.
