Well, each of the three issues you describe above have IETF drafts that are edging towards publication. These issues have been raised for some time. Some, e.g. DHCPv6 route option, invoke quite strong views, while others, e.g. ND cache exhaustion, are much simpler to address.

These are excellent... good writeups.

I share Owen's view - there are tradeoffs in deployment, and those vary with the scenario. And similar tradeoffs happen with IPv4.
