Most of users will want the key to just toggle wlan/bluetooth. But some of them
will be happy if they can configure the behavior of the key (cycle, only toggle
WLAN, etc...)

I thought just direct disable the default EC behavior then leave a
userland daemon to control the behavior, it will grab the wifi key event
then control rfkill state by follow user's customization rules.

What I'm saying is: I don't really care what's the default behavior is,
but if the EC provide a somewhat reliable way to make the key work
without any userspace daemon involved, I think we should allow
the user to use this mode (even if it's with an obscure module
parameter or sysfs file).

But .. maybe if someone want this default "raw" behavior,
he should just not load this module.

Fully understood, now.

Like you siad, we need define a policy for:

 - If user want the default "raw" behavior, what do they need to do?
	I thought if the wmi driver doesn't load by default, then user 
       will get a "raw" behavior.

But... 
The wmi driver doesn't just provide the RF switch function, it's also
have other functions like transfer wmi event to key code.

User doesn't load wmi driver will have "raw" RF switch behavior, but
lost other more functions.

 - If any distro want provide userland solution, how can they disable 
   the default "raw" behavior?
	If anybody want to disable the "raw" behavior, just load the wmi 
       driver.

Maybe we still add kernel module parameter?
