Goswin asked for a way to test d-i and friends with xz .debs, and this
script works well for that task, removing the need for recompiling.
No one proposes replacing packages in the archive without bumping the
version number, that'd be a recipe for disaster.
Although, if I understand what David Kalnischkies says in
https://lists.debian.org/debian-devel/2012/05/msg00706.html, having
packages with different size/global checksum but identical contents
(control.tar, data.tar) in local repositories (apt-cdrom, reprepro, ...)
shouldn't be a problem as well.

How exactly is greatly reducing download sizes a "stop gap measure"?
Obviously, several releases later the savings will be eaten, but without
them the bloat will be that much bigger. That's the long-term benefit, and
that it also solves a short-term problem (CD1) is a reason to switch to xz
before wheezy.

While dropping GNOME3 is a very sweet idea -- its main mode fails to work
on a good part of, even new, machines, not degrading gracefully; its
fallback mode is a bad joke, it Depends: network-manager (ie, Conflicts:
working networking), and so on, not to even start about more subjective
opinions about changes to the UI -- reducing the size of CD1 to 2/3 would
easily solve the problem for now and last for a few Debian releases, and
by then, CDs will go away the way floppies did.
