Well, zz is the successor of lzma. It's supported as "dist compression" by modern autoconf's (autoconf-2.64), it's the internal compression being used in rpm on modern Linux distros (Fedora, openSUSE), etc. Whether it's stable enough and has a longer term perspective is a different question or will prove to be a yet another temporary anecdote in compression tools is hard to tell - doubts are justified, IMHO.
