As I posted in earlier mail, for *big* packages it could actually save
good amount of size "per package". The total space save in the whole
archive could be a few gigabytes. And almost all desktop machines
don't fail to allocate additional memory xz needs.
OK, anyone could type "apt-get install texlive-latex-extra-doc" on
lowmem machines to install 400 MiB documents and fail on
decompressing. But for what purpose? Practically no one needs to
install such big packages on non-desktop lowmem machines. IMO
bandwidth and mirror space are much more valuable than supporting
unlikely lowmem install combinations.
