Well, we can delete stuff but personally I don't see a big concern with
leaving things sitting there so long as they're not getting in anyone's
way - it's more effort to figure out if there's any users (like with
this if there's people with old boards somewhere even if the product
isn't being sold yet) than it is just to leave things sitting there.  If
you don't want to do any support on it that's fine though.
