The existing codebase needs to be maintained, while building the new one. There are architectural patterns to help with the step-by-step migration. You could have also found someone to help maintain it, while you work on the new version.

I just hardcoded a link to your relay view into Alexandria, yesterday, and I'm totally gritting my teeth at needing to rely on you to maintain that view. That shouldn't be making me so nervous. I can't work with tools that don't get repaired, when they are broken.

So, I can add "Build relay view" to my ever-growing list of Nostr functionality that I am building in order to build.
