You have to remember that the Commision is comprised of boses who are looking out for their own interests more than they are for LCN as a whole. Most of the hits you mentioned had informal approval prior to the hit teams making their move. I have to think that if it comes down to the Bosses putting themselves in harms way, via indictments for a hit that has nothing to do with their family or money, or just peacefully working with the new boss, they are going to work with whoever is in charge. Throughout history the commision has played more of a mediator in disputes (most times only when the disputes brought unwanted exposure to press or law enforcement and potentially cost them money). I guess you could say that the commision is somewhat a paper tiger, although not one i'd like to get in a cage with.
