I'm not going to police the language in anyone's code, but some teams I'm in have moved away from the whitelist/blacklist terminology to allowlist/denylist

All really helpful feedback, thank you! Agree with that weird terminology.

This is looking really great to me, I had a suggestion around being able to configure your node to not support any schema ids.

Am i correct understanding that the default for a node without any custom configurations is that it is "ephemeral" (no db or identity state is persisted)?

Thanks for your comments @jadehopepunk all really useful!
