Right.

Having it there made about as much sense to me as having the supportede
channel width there :)
Got any better suggestions?

I mostly pushed it for 3.15, because right now you can already enable
DFS and it will bring it up on a FCC regdomain and it will appear to be
working (but probably just not recognize any radars).

However, now that I look at the description of the options that you have
to enable, it should be clear enough that this is not guaranteed to be
functional yet, so I guess it can wait for 3.16.
