> In cases where a model objects (as opposed to the adaptable Resources) need to be validated programmatically, the options at present are to have the PostConstruct method throw an Exception or to have a special method which clients use to determine if the object is valid. The former adds unnecessary noise to the log files and the latter puts undue complexity on clients.
> It should be possible to return {{false}} from the PostConstruct method and for this to be considered a signal for a null value to be returned from the adaptTo() method (without extra logging). For the createModel() cases, we can't return null and have to throw an exception.
