It is very tempting to use the model that you describe, but radio networks can be "flimsy" because of interference, signal fading, movement, etc.. The broadcast model for neighbor discovery/maintenance can quickly become unusable for nodes that loose connectivity to the DR. It is very easy to see how the same L2 media may provide nodes that don't have the same view of the other nodes (not everyone is within radio range of everyone else, for example). This brings me to wanting to establish p2p adjacencies while using the broadcast capabilities of the media to reach whoever is within transmission range (to propagate Hellos and to flood LSAs). The recognition that the characteristics between nodes can be different should also result in the recognition that the adjacencies between pairs of nodes may not all have the same state at the same time.
