The IP addresses you see as an AWS customer aren’t the same used to route packets between hosts. That said, there’s a huge amount of commodity infrastructure built up that understands IP addresses and routing layers, so unless a new scheme offers tremendous benefits, it won’t get adoption.
At least from a security perspective though ip acl’s are falling out of favor to service based identities, which is a good thing.
