That's not really what I meant. 

80/20 is fine except that we usually have no measurement to evaluate on
which side of the 80/20 frontier a feature is and 80/20 becomes just an
easy way to reject features we don't like.

Digression: for programmers an alternative to 80/20 is XP (extreme
programming). Unfortunately that doesn't seem easy to adapt for
specification authors.

Did you know it? Python has now a Relax NG (partial) implementation.
