Many of the ISPs I've worked with around the world have followed this path - and they are quite happy. I really think there is absolutely no need to consider full mesh iBGP any more. I wouldn't go as far as saying it's history, but I find it very hard to make an operational case for deploying full mesh iBGP any more.
One of the main problems of route reflection is that the best path decision is done centrally. The best route is not seen as from the router making the forwarding decision, but from the route reflector's point of view. Depending on network topology, geographic spread end peering/transit topo, this might/will have significant negative effects.
