I haven't even caught wind of this not being supported yet. No demand ==
no reason to include it when it does become available.

I've not kept a list. Would be non-trivial to go through the bug tracker
to find this info. Mostly it's things like webcams, and wacky little
hardware that starts cropping up in laptops.

Right, I think reverse engineering does help in that aspect. The other
aspect is that they now have a driver that sort of works for their
hardware. Most of the work is done, and they decide to help things along
to make it stable. So laying ground work like this can have advantages.

I think hardware vendors are a lot like users. Once they see the
advantages to opening up their drivers, they wonder why they didn't do
it a long time ago. Sort of like how users need that one push to use
Linux, and they start to wonder why they should go back to Windows.
