Thank you for all the explanations on how to use regtest to reproduce the example scenarios. It seems like a private mode wouldn't be particularly helpful for testing so I won't create a pull request and will just work on the private chains separately from bitcoind. Going back to chainparam modes

Not necessarily. Running a private server involves listening to the p2p network for incoming transactions, performing validation on receipt and organizing a mempool, performing transaction selection, and relaying blocks to auditors - none of which is tested in a reindex. A reindex would give you a
