Parental controls are a strange beast. In general, they stand zero chance against even mildly interested kid, unless you're going to lock them up in a basement to isolate them entirely from their peer group. Those controls work best as a soft limit - strong enough that going around them would be clear, unambiguous disobedience. After all, they're parental controls, not NSA-proof security. Making them technically bulletproof would arguably be worse for everyone.

Which could very likely go undetected, therefore unpunished. It's not like it's a family-room computer that's easily monitored.

It sounds like they're about as bulletproof as as screen door. I would be much better to have them as strong as an locked exterior door, maybe not "NSA-proof" (the door is vulnerable to locksmiths and battering rams) but strong enough to keep a kid out.
I think you're describing the point of view of the phone makers. Parents I've interacted with are in a whole other world. If you limit YouTube, you're limiting YouTube. There should be no caveats.
I'm a parent myself. But I also keep in mind that I owe my career and life comfort mostly to my parents being clueless about technology and too busy to supervise my use of computers since I was 9 or so.
