IMO WMI should not exist.
A lot laptop BIOSes do not use it at all, unfortunately it seems to get
more common again.
What advantage do you get on Linux using WMI?

For example HP is using WMI to export a WLAN (or bluetooth?) button on
some machines.
They should not do that, right?

AFAIK most vendors tend to send an ordinary key event again for most
extra buttons. Is this the way to go for the future? This probably
should also be mentioned then.
