Systems like SDF have an enormous rich history of implementing technology but the what, how, and why seems lost.
In a corporate environment, this knowledge is often passed down (or later inferred) because it must be but unavailable to the masses.
I couldn’t technically recreate SDF if I wanted to. I can build something functionally similar but the components would be very different.
(That being said, today I'd probably opt for Discourse and a nice TUI client)
