The only way the old dpkg will *use* a versioned provide is if the dependency on it is *unversioned*, so it makes little difference WRT backwards compatibility in tools. It does mean that to satisfy some dependencies, you will need to upgrade to woody dpkg/dselect/apt before proceeding with a potato->woody upgrade, but that didn't bother us with the current slink to potato upgrade.
