That's another story. For these devices, you can do what you want in
user space. But for other correct behavioured devices, bypass regulatory
framework is necessary. Because you have to trust the driver anyway.

The problem a driver is not able to give a SKU as regulatory hint.

It has nothing to do with ourdated rules. If a reg_rule is "wrong" in a
device, it will still be wrong after the regulatory_hint() call.

The current regulatory framework 100% trust the alpha2 or regdomain the
driver provided. Thus it should also trust a hint from driver "bypass
your regulatory check, I'll handle it myself".
