There is no way you can get to remotely effective parental controls that way. If the device is under control of the child/teenager, parental controls can (and often will) be circumvented. Without outside help and an extraordinary level of technical proficiency, this is not possible in case of parental control at the router level. Most of that 'industry' you are referring to are snake-oil salespeople who are selling objectively inadequate 'solutions'. To repeat what David Singer has said before: let us not exclude use-cases, just acknowledge that we've been focusing on browsers on desktops/laptops without meaning to make life for other types of user agents harder. And move on. As a rule of thumb: any issue that tries to fix a problem that in real-life only can be detected based on user agent strings should be closed since if you are at the point you do not trust a user agent regarding a DNT preference you cannot trust the user agent string either. That applies to plugins, extensions, routers, whatever. Because as soon you start sending a 'D' flag the next step for plugin makers will be to drop advertising their presence in the user agent string. So you're getting nothing in return for overly complicating the TPE. Which is hardly constructive.
