xz compression is slow (not bzip2 slow, but still slow). At least
it decompresses fast. I would think for people running stable, the
compression time would not be a big deal given how infrrequent it is.
If you are running sid, well that could start to get annoying if you
don't actually need the extra compression on your system.
