Toothiness

If this were adopted in full, how much would it actually bite?

Does the solution change the underlying incentive, or does it only change what people say?

The scale

1. 1Purely symbolic
2. 2Mild nudge
3. 3Real but evadable
4. 4Hard to route around
5. 5Changes the incentive outright

Five is the good end on every criterion, so no row reads backwards.
