I don't think its helpful to discredit all the other technical advantages of v6. Address assignment and configuration is significantly better under SLAAC than DHCP, multicasting actually makes sense, and routing logic and packet format are simplified.

If you were to try implementing a router for ipv4 and v6 the v6 one would be dramatically simplier with a lot fewer convoluted edge cases.

I actually specifically do regard (most of) v6's additional features as a bug; I think most of them could and therefore should have been implemented as separate protocols (consider ipsec, which actually did get pulled out and back ported to 4). I think the protocol we ended up with suffers from horrible second system effect and its scope creep it's part of the reason why it's taken decades to get mass adoption.
