I've not researched it, or spoken with our toxicologist, but I suspect the 
'safety' is as you initially described it - secondary consumers(animals 
consuming the initially poisoned rats/mice) are relatively safe from 
toxicosis - which is definitely not the case with most of the potentiated 
anticoagulant baits(brodifacoum, diphacinone,etc.).
I wouldn't consider the Vitamin D analogs to be 'safe' for any non-rodent, 
if consumed directly.  While the cases of Rampage/Quintox poisoning I've 
seen in dogs were mainly in puppies, they weren't necessarily 'small' - one 
was a 50-60 lb Lab.  And I've also seen reports of the same sort of tissue 
mineralization(stomach, kidney, lung) and death in adult swine, when their 
ration was mis-formulated, with substitution of Vitamin D concentrate in 
place of dicalcium phosphate.
