I don't think it is useful to sign the Packages file, because:

Any such key would have to be considered insecure, no matter how soon you
revoke it. So the paranoid people still don't trust it, and the other don't

Packages should come with their *.changes file, and dpkg should have an
option to verify the signature of individual packages. There was some
discussion about this in the past. The trick is that security should be
implemented in dpkg(-dev), not somewhere else. This has the advantage that
it works also with individual packages you don't get from an archive source.
It cuold also be used to verify the origin of the package.
