There is also a human economy here. An "exclusive" subnet implies membership: administrators with access keys, SREs with runbooks, developers who push commits to gated repositories. Policies are negotiated like social contracts: who may provision, who may observe, who may cross from the general-purpose net into this curated domain. Each decision — which ports to open, which subnets to peer with, which logs to retain — carves the identity of the enclave. Its cultural signature is as important as its configuration: careful, custodial, perhaps proprietary.
