What a waste of time. Boarding passes are not designed the way they are to be helpful to the passenger!
If you put the seat diagram or the boarding priority on the pass, people will demand those things. The airline needs to be able to shift you around. Actually printing Economy instead of Y will cheapen the experience.
Finally, it won't help the airlines/airport squeeze you for more in-flight purchases. Let's face it, the whole flying experience is designed around selling you extra stuff.
