I'm not sure it will be better. Non-stop mode is not purely a property
of target, encapsulated inside it. Rather, it's global property, which 
must be supported by target, so enabling it in core, after making sure 
that target is fine with that, seems reasonable. In other words, 
'enter_non_stop_mode' target method cannot do much except for emitting
an error if non stop is not supported, therefore a method which just reports
support for non-stop seems exactly right choice.
