Spare disk space isn't available to add amd64 to mirrors.
Spare bandwith isn't available to add amd64 to mirrors.

Users disk space might be cheap but they have the unpacked binaries

Users bandwith might be cheap but often very limited due to
infrastructure. A lot of analog modems are still out there.

Any arch where cpu speed still grows has plenty of cpu time to spare
anyway. Only old archs (and the embedded stuff) have cpu problems. But
do they want a 200MB OpenOffice?

Where do you get this from? Where is this relevant?

The overhead to change to a new deb format is small. A very few
packages have to change (dpkg, apt, DAK, mini-dinstall). A few man
hours of work and compared with the amount of changes in debian every
day that is miniscule.

The transition itself would go completly unadministered. Once dpkg is
switched to default to a different compression all freshly build
packages use it and the archive transitions itself over time.

All the transition needs, after the initial infrastructure change, is
a lot of time. At least one stable release to get stable dpkg to cope
with differently compressed unstable packages and then time for every
package to get a new upload.

Don't forget CD/DVD space. With better compression you could probably
fit Sarge i386 on a dual layer dvd again.

The businesscard and netboot images would also shrink alowing some
more debs on them, e.g. a graphical installer.
