It would have an edge if it had inbuilt protection against spoofing. However now that there are big actors that profit off DDoS mitigation....

Or any other feature genuinely lacking from IPv4. Merely having unique address for every grain of sand on the planet isn't enough.

Don't many botnets use compromised machines now? Protocol level mitigations wouldn't help that would it?

It would make blacklisting compromised networks easier at least.
