Broken? That's a strong word. Tricky perhaps. Best avoided by novices, yes. 
But broken? Do they not work exactly as described in the fine manual?
FWIW, I still see them a lot in the wild.

feature yet (exhibit A: updateable views), it's a moot point unless 
the goal is to spur development of those features just so we can 
deprecate rules.
