I indeed said exactly that: always build against what has already made it to

Lack of autobuilders can be remedied. Pinning is of course difficult when
package versions are in constant flux.

Why can't everything just be cross-compiled on a _really_ fast 64-bit host
belonging to the Debian project? Couldn't e.g. IBM or HP (who both support
Debian in some way or another) allocate some hosts for that, for instance?

...or to safeguard oneself against unfortunate incidents. I use the following
preferences, by default, on all my hosts and on those I install for others:
Pin: release a=stable
Pin: release a=testing
Pin: release a=unstable
Pin: release a=experimental
This ensures that selected packages can be easily pulled from Testing and that
others can be also pulled from Unstable, if they don't require any dependencies
that cannot be satisfied by Testing.
IMHO, these defaults should be installed by debootstrap, on a virgin system.
