I disagree that this is a one-time action, people might want to
cross-grade specific packages back and forth, not just the entire
installation. Also unsafe cross-grade does not only affect the
Essential set, it also affects anything involved in the boot process,
if for whatever reason the system crashes and apt would have removed
such package the system would be rendered unbootable.

I guess I don't see the additional complexity in the dpkg specific
case, it just needs the shared libraries to be installed which should
be co-installable anyway, and the rest being M-A:foreign.
