But this is the problem that most designs are trying to solve. Large L2s are notoriously fragile. 1,000 nodes, 50-100 pods/node is a lot of ARPs. And sometimes you want partitions between endpoints for security/isolation.

I agree with you about static assignment of addresses. But that's why (most) CNIs work with a controller of some kind for IPAM.

IMO, the problem complexity is hard to compress. You need to distribute/manage MAC addresses, routes, and/or state. Different designs would favor one over another.

but thats what subnets are _for_ nobody in thier right mind runs more than a /22 on a VLAN/partition.

In this case I think the traditional model works well, has excellent documentation, and scale much better than the alternatives, especailly in AWS.
