You need it to be supported in stable before using it in unstable. So at best,
you would need to implement it in Squeeze and wait for Squeeze+1 to use it.

This requirement is here to ensure smooth upgrade (stable -> testing (or new stable)
with dpkg from stable). So it stand for .bzip2 and .lzma support in *binary* packages.

Charles is talking about *sources* packages.
Some packages in testing already require other packages from testing to build
themselves (ie build-depends nor present in stable). This is catch by debbuild for

Unpacking a source package is not needed during an upgrade. However, it occurs before
a build.

So, I understand the question of Charles as "do we want that stable dpkg be able to
unpack all packages from testing ?". I have no strong opinion for this.

In stable servers I use sometime the sources of unstable/testing and I backport them.
So I would like to have package compatibility "actual stable" to "actual unstable".

I do this things only on small packages, so I don't want to upgrade/backport dpkg.

Anyway such things are not a common usage which should be supported, so I can
live also with a breaking source package compatibility.
