Optimality is in the eye of the operator.

What MAP does is *minimize* the amount of state at the cost of
flexibility. It may be more or less optimal depending on what you need.

Suggestion: create a two-axis ASCII graph labeled "state" and
"flexibility". Put MAP, lw4o6, and heck even DS-Lite in it at the
appropriate spots.

(This is not wordsmithing since I'm proposing a figure. It's
figure-smithing.)
