Recycling a post about reasons to do it that way:

> 1. Most of the dollar costs of making it all happen will be paid by the people who actually need/use the feature.

> 2. No toxic Orwellian panopticon.

> 3. Key enforcement falls into a realm non-technical parents can actually observe and act upon: What device is little Timmy holding?

> 4. Every site in the world will not need a monthly update to handle Elbonia's rite of manhood on the 17th lunar year to make it permitted to see bare ankles. Instead, parents of that region/religion can download their own damn plugin.
