I don't think this is necessary; bloat (http://bloat.sf.net) can do this

On the contrary, I'd say it might help on cmd-line.
In a script, you can easily do something like

case $archive in
*.gz) dec="gzip -dc";;
*.bz2) dec="bzip2 -dc";;
esac
$dec "$archive" | tar xvf -

rzip cannot decompress to stdout, so it might be a bit tricky:

rzip -kdo "${archive%.rz}" "$archive"
tar xvf "${archive%.rz}"
rm "${archive%.rz}"
