Yes, probably.  My priority is to hash out the classification
first though, so it isn't in this series yet.

On the cmd line switches:  How much flexibility do we want on this?  We
can go for a simple -future switch, as suggested by armbru, disallowing
obsolete and deprecated devices.  We could go for a full-blown ...

  -policy {experimental,unsupported,...}={enable,warn,disable}

... or something inbetween.

Comments?  Other ideas?
