I'm not saying about we should remove drivers, my worry is only that we
don't have two drivers competing about same devices in a normal distro
kernel. We should _by default_ not have two drivers claiming support for
the same device, developer's can of course enable this via experimental
options etc.

Sure, that's up to them. I don't care what's in staging so I can't
really comment about that, this is only in context of
drivers/net/wireless/.

That sounds good. Let's just make it as obvious as possible that distros
and normal users should enable that option.
