Indexed access. Tarballs, unlike, say, zip or 7zip, don’t normally support jumping right to the point in an archive where a file lives. It’s LZMA-based, like xz, lzip, or 7zip. Good-but-slow compression, faster decompression than bzip.

In the POSIX standard, it has officially been replaced. de facto standard as by users, it has remained dominant. We have just not been following POSIX as closely as we could (and we don’t have any reason to).
