That feature isn't what I think the parent comment is asking for. What you've linked to is specifically YouTube Kids, and it's groups of channels whitelisted by the YouTube team. What I think the parent comment is asking for, and I want too, is full availability of all YouTube channels, but the ability to block everything except whitelisted channels. I agree, it's too niche a product. But I often think that people whose response to complaints about kids' access to inappropriate content is "you need to parent your kids" is fine, but I need the tools to do that! A tool like this would be a godsend.
