It is an obscure alternative to zip if you look at the file format. The
only reason why it got even semi-popular was the compression algorithm.
The compression algorithm is essentially what you get with .tar.xz too.
My point here is that the proliferation of obscure formats shouldn't be
encouraged and therefore vendors should be asked to use sensible
You argued that .tar.xz is painful to create in the Windows world.
I agree that it is more work, but for users in the Windows world .7z is
painful too (just like rar and whatever), as it requires Yet Another
Program to handle something, when Windows supports zip files out of the
box. Or to put it into a different perspective: XZ is very likely to
fully replace tar.gz for most areas, which it very unlikely to happen
