I don't think that was the problem.  The IETF wonks saw MD5 authentication 
on OSPFv2 as a dirty hack, rather than as a quick and easy means of 
providing a 99.99% solution to OSPF authentication.  Instead, they wanted a 
100% solution, and in their opinion IPsec was the way to do this because it 
provided a cryptographically sound framework for authentication and 
encryption services.  So they mandated that there should be no MD5 
authentication for OSPFv3, just IPsec.

As hooking anything into IPsec tends to be difficult (there is no 
standardised API, and it's a pretty gargantuan framework), ospfv3 
authentication is not implemented on many platforms.

Perfection is the enemy of good enough.
