Read the proposal... I have an aversion to-go coffee cups that remind people that hot coffee may burn them, and when my daughter was 4 we explained to her why knives were to be handled with care, rather than remove them all from her sight. IMHO the proposal evoques mandating training wheels rather than letting people learn naturally from their errors.
