They probably will. The question is, how far out-of-spec should the
kernel allow by default? 200% is likely to be too far (your plugpacks
notwithstanding).
I would say by default the kernel should not allow any out-of-spec power
condition. Some devices might decide to go into over-current mode if a
device draws too much power, taking down other devices on the USB bus.
This sort of behavior should only be enabled if the user explicitly
chooses to live dangerously.
Especially given the fact that Windows enforces the USB power supply
limits strictly, and that's where all the hardware is best tested..
