i didn't say "legacy isn't supported at all".  xz will work on legacy systems 
just fine provided you d/l and build the decompressor (which is freely 
available).  what i did say is that we can't restrict ourselves based on what 
random old versions of tar people have on their random systems which happens 
to not detect xz transparently.

your `tar` doesn't support -J, or -I, or -a doesn't detect xz ?  then run 
`unxz` yourself first.  there is no actual problem here.  the only thing i've 
seen from Eli is that he doesn't want to have to run `unxz ... && tar xf ...`.
