I don't even want updatable views!

I'm looking through those archives and its vague what killed them, but bad rules
are definitely part of it. However, that doesn't mean you ditch the rule system
because it didn't work for this particular situation.

Maybe you could highlight some messages that point to the precise corner cases
that make rules so bad? I would expect these corner cases would have nothing to
do with updatable views, since they are such a bad idea to have automatically
implemented.
