For example, an operator adopt OSPF to use its rich routing feature but the network is small, the operator does just area 0 routing, even OSPF allow inter-area routing for scale. Is an another ospf specification needed for 'OSPF Area 0 Only Routing'?

Well if I only have a simple network and I uses RIP, you don't make
OSPF somehow compatible with RIP(or just include RIP with an OSPF
terminology face? I don't know) and say "hey, just use this super
suite, don't consider it overloaded, it's for unity!"
