Right. That's a separate discussion though - whether we add two flags
here or check NEW_KEY support doesn't really matter, except that we
need to decide

 * if we want to support such an override at all, and
 * if it should be tested at all
   (perhaps we can just live with that failing entirely?)

I don't really know. I personally don't think that we need to allow
both ways, but then I'm coming with a driver that doesn't even support
the old way.

So you should probably decide yourself if you want to keep this
fallback option, and how well it should work (be rejected if used on a
driver that doesn't support it, or just fail later?)
