I would like to see the samesave(), destroy(), etc. on the returned item instances by default. Is there currently a reason why they aren't?

// Example codeModelName.find(1).then(function(item){item.destroy();});

For the mean time I am adding them withdefineResource().

varModel=DS.defineResource({name:'subjects',methods:{destroy:function(){returnModel.destroy(this.id);}}});
