Those, when hearing of a new 'Commodore Amiga' will quickly become disallusioned when they realise it doesn't actually run Amiga OS.
Those that would like the experience of running a 1980's/90's OS would be probably be disappointed, yes. But I'd say those that want an OS that is usable in today's world will not miss any Amiga(oid) OS at all, as they stand today.
