That's a neat idea, and it might help - but it's not the kind of problem governments would chose to solve.

Or put another way, governments would chose to intervene by helping to create more 'competition' - which creates product variations approximating true market needs - as opposed to trying to 'legislate features'. 'Feature lists today' but something else tommorow. If the market is healthy, it will move in the direction of value, is the idea.

Governments can also help by promoting and supporting standards.
