What next? The kernel checks to see if you are overclocking your processor and refuses to boot? The kernel determines your network cable is too long and disables networking? Why not produce a prominent warning instead of breaking functionality?

Putting a lid on USB power

Well overclocking is a conscious action very difficult to perform by accident, plugging in one too many devices on the other hand is very easy. So the potential in doing damage to your system is much greater. I have a bunch of USB devices, but I have no idea how much juice they need or how much the ports on my system can provide (or should provide according to the specs) so yes I would like my OS to protect my system and my devices.

And if attaching network cable that is too long can result in damage to my system I would certainly like the OS to turn off networking!

Of course, this being Linux and all I would also expect a way to turn those checks off if you really know what you are doing :-)
