Seems unsafe to telegraph to the web that a device is being handled by an underage user. And redundant, since that would probably require some intervention from the user/client to set up, who could already block adult websites on devices anyway. If they're capturing the edge case of parents who do nothing, but expect their kids to be protected when they hand them a tablet, I don't think there's much to do. Seems way more effective, with no downsides, to just communicate to parents on the govt's part. Adult streaming sites have the "are you 18 years of age?" pop-up. As far as those managing the sites are concerned that should be enough.
