Well you commented on hardware, so.

If its entirely untested (due to being unsupported), it should not be
made available, and instead be added once it is supported and has been
confirmed to be working properly.
There is also no reason to add it if we know it doesn't work, it would
just be misleading to add an option, which then shows up in the help
output, if we already know it doesnt work anywhere (yet).
